Announcements Software Upgrades Linux

2.6.13 Linux Kernel Released 464

LynuxFre@k writes "Linux Torvalds announced the release of the 2.6.13 Linux kernel. He noted that there was a major change to the x86 PCI code, and that while all bugs from the change were believed to be found during the release candidate phase, it's possible that some devices may have problems. From this release on, it is intended that major changes only be merged into the kernel within two weeks after a major release. The rest of the time will be spent fixing bugs, with the goal of both increasing overall stability and decreasing the amount of time between major releases.

      I wish Linus would just stick with fixing bugs in stable releases and leave major changes to development versions, but I guess that'd take finding him a new toy to play with.

      • Developement-version = 2.6.x and 2-6.x-mmz

        Stable-version: 2.6.x.y and vendor-kernels

        Maybe things were named differently in the past. But what matters is they way they are named today.

      As long as things aren't changing bimonthly, I don't see a horrendous problem. There's much to be said for being flexible.

      Then again, if it happens too often, more time is spent switching back and forth between the new "great" ideas than doing actual work.

        When I can't find a stable kernel for one of my servers, it's a serious problem.

        It's been hard to get long uptimes with 2.6... the network drivers are leaky/crash, SCSI support sucks.

There are plenty of things that seem far more urgent, like releasing a kernel that's actually stable (it's at the stage that I'd go back to 2.4 if my distro didn't have so many things depending on 2.6).

      It's not THAT bad. Revision control system has been changed twice during the lifetime of the kernel. Developement-method has been changed once, and now that method is simply being tweaked a bit. And what do you care how they develop the kernel? Are you are kernel-developer?

      Or how would you like them to do it? "We will do things this way, and by god, we will do it like this untill the end of time! Even if better ways of doing this comes along, we will not change our ways!"

      Well I'm fairly sure Linus has a better handle on all the issues than you do.

      But... gee, if it bothers you that much you can point Andrew Morton to your kernel tree, or send him your patches. He does a pretty good job of ensuring things don't clash, and queues it up and merges with Linus, getting initial bug testing and review along the way.

RHEL 3 was released quite some time ago, and the 2.4 kernel that was provided was probably heavy patched, since RedHat has quite a number of kernel hackers employed. RHEL 4 features a 2.6 kernel.

    I've been using Linux since 2.0.27. It has usually been generally quite stable for me. But recently, I've been encountering more and more kernel crashes. For trivial things to, like a kernel crash when I try to use ifconfig yesterday when setting up a machine. And random crashes on one of my servers that doesn't seem related to RAM. I know that some kernel versions have "problems", but it seems to be more than that. A recent trend of unstability. Can anyone else who has been using Linux for a significant amount of time attest to this?
    • Can't say I've noticed kernel problems of late, and I tend to use the ck branch. Been having freezes, but that was heat-related in one case, and dodgy nvidia drivers in the other.
    • I've had a few lock ups recently but I tend to blame the GLX module [happens with GL enabled XMMS plugins]. The kernel doesn't lock but XMMS basically rapes the cpu.

      As for instability I've been able to boot/run Linux on pretty much anything. Laptops are fairly bad for standards compliance and some cheaper mobos like MSI are not too friendly.

      Stick with ASUS or Gigabyte mobos, use dlink or broadcom networking, use nvidia GFX, etc... basically use HW from people who are linux friendly. :-)

          My only complaint with 2.6.12.x is that the timer is poorly based on TSC [hint: cpufreq changes the TSC rate!!!]. So I keep losing time. Fortunately I've mitigated this through a */10 in my crontab and I run rdate.... it's a poor fix but for now will do.

      Yes, unfortunately I have the same experience. I used to rely on the vanilla Linux kernel tree being rock solid. Now I feel I must stay many months behind in order to avoid potentially catastrophic problems. Considering the number of bug fixes, particularly w/ regard to security, that can show up in new kernel releases, it's not an ideal situation: you're damned if you do, and you're damned if you don't.

      I've recently had networking go south when packets were being written to localhost. Some adaptec scsi stuff was recently messed up, apparently now fixed in 2.6.13 - but no way I'm going to try it until it's been out for a while. I've seen problems with quotas in combination with ext3. I recently started experiencing connection tracking weirdnesses with an iptables setup I've used at home for probably a couple of years. I've seen versions where network latencies would grow ever so slowly until they reached a critical threshold that sent my server(s) spiraling into oblivion. Yes, I file bug reports. Yes, problems get fixed. But at the same time, new ones show up. Sometimes bad ones.

      I've become accustomed to rebooting Windows to fix problems, but that's exactly why I use Linux - because it was rock solid. I won't say that anymore, and it bums me out big time. I like new shiny objects too, but not at the expense of stability. Especially not on servers, which is where Linux has made the most headway.

      The problem with the current versioning system is that even if there is a bug-fix only decimal release, and even if there is only a two week window to introduce new features, the bug fixing won't get done. Why? Because new features are more fun than fixing bugs. Even if I can't submit a new feature until several months from now, that doesn't mean I won't work on it in leiu of fixing bugs.

      Linus should freeze the 2.6 kernel series against *any* new features at all, for a period of about a year. All work should be on increasing stability, ironing out bugs, improving device drivers, and other such menial housekeeping. The kernel contributers who really buck up, get to work, and help with this effort should get big karma bonuses from Linus. Those who hang back and work on their own thing should be pushed down a level in future kernel submission evaluations.

      Sorry to be so negative, but I really hope this gets better. I'm a huge fan, but I have been wasting way too much time lately dealing with problems that end up being way beyond my control. When there is a problem with my systems, I want it to be my fault, because then I can do something about it.
    • I attest that I have seen a surge of unstability on my Linux machines.
      And I can also attest that all the kernel panics or lock ups where due to hardware problems : SCSI and IDE disks crashing; IDE cdroms dieing, killing the IDE port entirely; mobo dieing.
      Actually, I think this must be due to the fact that my Linux machines run 24/24 7/7 since 2001 and that some components had never been replaced.

      Are these crashes repeatable or do they have any kind of similarity?

      I've been using Linux since 0.9x, and its been very stable for me over the years with a few exceptions that were experienced by other people as well.

      My first assumption when I have a seemingly random kernel crash with no meaningful data from the OOPs or other messages is that there is a problem with my hardware.

      For me, the Linux kernel is more robust than electrical power or hardware.

      YMMV.

      But it's very hard to generalize from one person's experience to any general "recent trend of unstability." Most of the bugs are in drivers, so people's experiences tend to be highly dependent on exactly which hardware they have.

      I've been using it since 1.2.13, and my experience has been the opposite: a 2.0.x had a "ping of death" bug; I skipped 2.2.x until I already needed features not available in it; 2.4.x was generally stable; early 2.6.x had a bug where it would sometimes not set up the keyboard or mouse correctly; and recent 2.6.x has had no problems at all.

      Have you tried reporting these crashes? I can't find anything about ifconfig triggering crashes. They can't test everything themselves, because they don't have every hardware configuration, so it's important for people who do to tell them when something is wrong.

    Okay, this is something that's been on my mind a while, so I hope it'll get some amount of attention and hopefully an interesting reply or two.

    I also hope it's not going to get modded down to the seventh level of hell, as I'm about to (gasp!) express disagreement with Linus.

    First of all, I am vaguely concerned about the Linux kernel development. It's been a long time since there's been major improvements under the hood. I've had Linux desktops freeze on me. In the past, that never happened. Ever. I don't know which kernels are trustworthy anymore. I've read something to the extent that stabilizing kernels is now considered the Linux commercial vendors' job. Excuse me, but WTF?

    In the meanwhile, while we Linux types wave our dicks around and gloat over how great we are, the guys at Redmond are happily making it possible to change video drivers in their OS on the fly, and to unload a crashed driver without taking down the system. Will it work? Probably not 100% well right away, but trust me, they WILL make it work or they'll die trying. And Windows 2000 is proof that they can certainly do things well when they put their minds to it.

    And Linux is about to become the unstable OS choice and it seriously pisses me off.

    A very long time ago, Linus Torvalds and Andrew Tanenbaum had a since famous argument about the core structure of the kernel.

    Linus's argument was, if my memory serves, that it all boils down to pushing bits around, and that you should as well push the bits in the simplest way.

    And this is where I disagree.

    Kernel development is about pushing around the bits that will push bits around. Those are the bits you want to push around in the simplest way. The goal is not simply to produce a good kernel, it's to produce a maintainable, efficiently improvable set of source that will compile into a good kernel. Otherwise, the end product you get is a good kernel for its time that will be a bitch to drag into the future.

    Perhaps the state of the Linux kernel development today is but Tanenbaum's schadenfreude.

    Assuming that kernel improvements have indeed, as is my admittedly fragmentary view, slowed down worryingly, I find myself wondering if, simply, now is when Tanenbaum should be speaking up, rather than all those years ago. The structural needs then were simple: few consumer devices, reduced architechtural diversity. Today's aren't. And there is STILL no 'just-works' way for third parties to deliver drivers to their customers. The least worse they can do is deliver sources to the kernel maintainers and hope that 1) they will be accepted, and 2) there won't be too many months between now and the moment their customer's OS uses that kernel. Or they can ship scripts that will compile glue code between their driver and the currently running kernel, and hope that the customer has a freaking compiler installed. I'm sorry, I can compile drivers and upgrade kernels manually, but neither are acceptable solutions for the mass market.

    In fact, I'll go out on a limb and predict that unless the kernel's structure and development processes are rethought to take into account the use of an OS as a three-party system -- the OS vendor, the user, and the commodity/paraphernalia providers -- Linux will never be a significant player in the desktop market.

    Thought on that? Please, please, please prove me wrong. I'm a long time Linux user, I did in my time the mandatory contributions to the kernel that allows me to speak up and bitch now, and from what I can see the future is not looking well for the Linux kernel. So please prove me wrong. Thanks.
    • I'd prove you wrong, but I stopped reading after you said that there's no major improvements "under the hood" (is there any part to the kernel that is not considered "under the hood") anymore. That claim alone shows that no matter how insightful you might otherwise be, you're completely out of touch with reality. :)
