Linux 2.6.0 Expected In Mid-December 270

Posted by timothy from the send-more-penguins dept.
Ridgelift writes "CRN is reporting the release of Linux 2.6.0 in mid-December. 'Torvalds, Linux's lead developer and now an OSDL Fellow, and Linux kernel maintainer Andrew Morton this week released the test10 version of Linux 2.6 after a three-year development effort. A final test11 version is expected before they sign off on the production version next month.' Get ready for 'major scalability improvements, faster performance, enhanced support for embedded systems and, to a lesser extent,' a kernel that 'supplies desktop systems with better USB and FireWire support.'"

    I've been running -testX kernels for a while now and the claims made about all the improvements are true -- 2.6 is a far better kernel than 2.4, IMO.

    The prediction that akpm made about mid-December sounds about right as well -- 2.6.0-test10 could be 2.6.0 right now and I doub there'd be any showstoppers to block it.

      What's taking so long anyway? I thought Linus's new grand master plan was quicker releases of major versions. 3 years seems like an eternity in the electronic world. In that time Windows has gone from 2000 to XP to 2003 for crying out loud! They're jumping all over the fscking version map and all we have to show for it is a lousy .2 subversion jump? 3

        "All good things come to those who wait."

      • But really, think about it.

        In the past 9-10 years, windows has gone from 3.x to 95 and NT, to 2000, to 2003. In the same time, Linux has gone from 1.0 to (just about) 2.6

        The biggest shift in windows-world was from 3.x to 9x / NT in 1995. Linux went from 1.2.x to 2.0 in 1996. Since then, we've had 2.2, 2.4, and 2.6, all of which have had improvements that would have qualified for major releases in windows.

        Of course, Linux is a kernel, and windows is quite a bit heavier, so it's a case of tangerines and or
        • Actually Win9x to NT was a major leap as that was when the 16-bit stuff was ditched. There was no corresponding revolution in Linux, just a *lot* of incremental changes. Although some changes were big, their scopes were a lot smaller and as you say, Linux is just a kernel.
          • Sure, it's picking nits, but still ...

            Windows went:
            1.x --> 2.x --> 3.x --> 95 --> 98 --> ME --> XP Home --> Longhorn

            Windows NT (completely separate beast) went:
            NT 3.x --> NT 4.x --> 2000 --> XP Pro --> Longhorn

            The only major shift were from 3.x to 95 (GUI and mostly 32-bit), and from ME to XP (GUI and fully 32-bit).
            • Picking even smaller nits, XP Home and XP Pro are very simmilar and both based on the 2000 kernel. The 2000 kernel was only really a evolutionary change from the NT. The big jump was going away from the 95/98/ME stuff. To be fair, Windows 2 (almost unusable) to Windows 3 (386 support) was also a pretty big one.

              Perhaps my perception of a more continual process with Linux is because the source changes and discussion groups are public.

        • Various versions of the XP kernel

        There has been some tweaking of the kernel for market positioning and bug fixes, but no other major architectual overhauls.

          The NT and XP kernel are the same. XP's is just an incremental improvement over the NT4 Kernel (it's almost the exact same Kernel in Win2000 aka NT5). Microsoft have just moved things in and out of the Kernel since NT3 to improve performance (such as the full DirectX support added to W2K rather than the awful DirectX emulation in NT4).

          Also, while it's true that the 9x series are built on top of DOS, the same as 3.11, there were a significant number of changes to support 32-bit and things like pre-emptive rather than cooperative multitasking. Not quite as many changes as Microsoft would have us believe (it certainly wasn't the 100% new 16-bit-free operating system everyone expected based on what they were saying), but certainly a lot of changes under the hood.

          Lastly, 3.x never had a Kernel, it was effectively a big graphical library and program launcher, and not much more.

          That given, I'd revise your list to:
          • DOS Kernel (if you can call it a Kernel!)
          • 9x Kernel (which built on DOS/3x)
          • NT Kernel (featuring in 2K and XP with tweaks)
          I agree entirely that Linux has to be taken in a larger context. Considering that in the same time it's taken to go from 2K to XP we've seen Gnome go from v1 to v2 and KDE go from v2 to v3, which were much more significant changes, I'd say that Linux on the desktop is advancing more rapidly.

          Besides, there's no reason to rewrite a Kernel from scratch if you get it right the first time. There don't seem to be that many fundamental problems with the Linux Kernel, so the continued process of tweaking and gradual improvement seems set to continue. Microsoft, on the other hand, had to write a new Kernel because 9x was such a horrendous mess and lacked quite a lot of modern features and elegance.

            You're correct, right up until you imply that NT was written to replace 9x. NT shipped before win95, and it existed within MS well before win95 was even conceived. win95 was writen because they wanted to ship win32 to customers and NT didn't run as well as OS/2 or Win3.1 on consumer-level machines.

            There was an effort to write a completely new win32-based replacement for win31, cougar was the codename for the 32-bit DOS kernel, and panther was the win32 core, but panther was canned and cougar was merged into chicago (win95).

    We're running 2.6.0-test9 on several production machines at work, and we had absolutely no problem, so far, but a huge improvement on performance instead. The only thing one has to care about is that 2.6.0 requires module-init-tools instead of modutils. It's especially important to read the upgrade guide, so that one can easily switch back to 2.4.x even when using modules (not that I would miss 2.4.x, but you never know... not all people will have such flawless upgrade processes as I did).

      It will save you countless headaches if you read the files about module-init. I have been using the linux kernels since 2.0x but never had an upgrade break a system. It totally ruined my redhat 9 box doing that.

      I upgraded to module-init and after that 2.4 wouldn't boot. grr.

      Is there a way to have both installed so I could dual boot 2.4 and 2.6?

    I've been wanting to run the 2.6 on my Debian-unstable box, but I've been scared off by some of the negative reports I've heard so far. Some of them I've seen on comments from this article [slashdot.org].

    Most notably (for me) is devfs not being actively supported anymore [slashdot.org] (being shifted in favor of udev). That's sad, at least for me, because I've been using devfs since the early versions of the 2.4 kernel, it always worked well for me, and from what I've heard about udev so far, devfs seems like a more elegant and mature solution.

    Then there are problems with USB devices, and others that, being narrowed down, comes down to problems on the APIC interface [slashdot.org]. From what I've heard so far, it doesn't look stable, so why ship it on linux 2.6?

    There's also this problem with Kernel Preemption [kerneltrap.org]. I'm using it on my 2.4, and I don't want to go without it on 2.6. Of course I might just be lucky to no stumble on this problem, but the fact that it can trigger an oops on someone just scares the hell out of me.

    Finally, there's a problem I've experienced myself, but didn't care to report at the time. It's quite old by now (I think it was around version 2.5.65~2.5.70). It has to do with software-raid. I've got a RAID-0 array with 3 SCSI Disks (6gb + 2x4gb = ~14Gb). The disks are old, I know, just like the controller (Adaptec AIC-7xxx). But they work just fine on the 2.4 kernel. So, at the time I decided to give 2.5 a try, just to find out that my array wasn't being detected/mounted. Googled around, found some similar reports and some possible workarounds, but none worked, so I switched back to the 2.4 kernel and haven't touched the development kernels since. It might just be resolved by now, I don't know... Anyway, I will soon replace these disks by a couple of IDEs, with no RAIDing, to save some CPU cycles, so this will not be such a big problem.

    So, anyone care to give me one (or more) reason s to try 2.6 again?

      Well, the reason devfs is not actively supported is because the maintainer disappeared, and nobody has stepped up to take over the code.

      udev seems to solve the problem of only have /dev files that correspond to devices you have connected. But they are moving "back" to the old /dev/sg?1 etc. I much prefer the devfs nameing scheme (what do you do if you have more than 24 hds? The devfs had a solution for that).
