      I just built and booted it on my Sun Ultra 60. CONFIG_PREEMPT seems broken on SPARC64, but after I removed a redefined symbol in ffb_drv.c, everything else seems to work.

      One interesting note is that the sun/type5 keymap/keyboard settings for the console/XF86Config don't work anymore. Had to revert to the kernel keymap for the console, and xfree86/pc101 for X11. Also had to change /dev/sunmouse::BusMouse to /dev/psaux::PS/2 in XF86Config, but the middle mouse button doesn't work now. Gonna figure out that

    I decided to test 2.6.0-test1 on one of my primary servers. After building the kernel, I had to install the Debian module-init-tools package (required to manipulate kernel modules in 2.6) and edit /etc/modprobe.conf to alias what module to load for my ethernet cards and for the PS/2 mouse driver (the "mousedev" module). And then it just ran. It's been serving perens.com for days.

    I am also running it on my Vaio U-101 (a Pentium 4 600 sub-laptop that fits in a fanny-pack).

      You're *exactly* the type of person who will make the best tester, precisely because it *will* crash for you. It's the tiny bugs that only show up under bizarre/rare combinations of features and usage that can be the most pesky.

      Now, I'm not saying you should run a non-stable version on your server, but what about setting up a spare machine simply to replicate what's being done on your server?

      Not only will it help out kernel development, it will also mean that you will get a stable kernel for your server sooner.

      • Thats exactly my point. The people who are in the best position to really test the kernel are the ones who require at least some level of stability to run at least for a few days before a crash. If I had a mission critical server, I'd just run 2.4.21. If I had redundant servers, I could run a test server in parallel, but I have one overloaded Pentium1 that connects 5 networks together and is a file/web/database/game server.

      Never try anything new on your production machines.

      Have a test server configured exactly (or as close as you can get) like your production server.

      Always test new software on the test machine before putting it on the production machine.

      This is important whether you're running Linux or Windows or whatever. Even when you're testing new versions or updates of apache or PHP or perl or postgresql or whatever.

      Running untested (by you) code on production servers is guaranteed to bite you eventually.

      Just save yourself the lost time and headaches and get a test box.

      Your time and data are worth far more than the cost on a test box.

    Here are some issues not discussed in the kernel documentation, that need to be resolved before technical users who know nothing about the kernel (like me) will be able to test the kernel in any meaningful way...

    How to configure support for Virtual Terminals?

    Using an install straight from the Debian Woody DVD-R, it can compile, boot and get to X. However there is absolutely no output from "loading kernel...", to the start of X, and cntl-alt-f1 gets be to an unchanged screen, not a login prompt. I know that VT support is not enabled by default (why?), but enabling VT and console on VT does not make any difference. Same thing happens with Mandrake 9.1.

    Are compile errors for default configuration OK?

    I thought I may have accidentally removed something required for VT support. So I made a completely default install, i.e. "make config" and hold down enter for all questions. However, this would not even compile on gcc 3.95.4 from Debian Woody. Are drivers that don't even compile enabled by default, or is the statement in the docs that any gcc 3.95.x where x>3 will be ok, out of date?

    Would getting the .config file from a working install of 2.6-test help?

    If so do you have a link?

    Why does make modules_install complain about missing dependencies?

    Why doesn't it just make the dependencies? What are we meant to do about this?

    Also, is NTFS write support ready for end-user testing in non-mission critical situations?

    • In Linux 2.6 the old NTFS driver support was removed and new better code [sf.net] installed instead. The NTFS write support is there, but very, very limited; the only good use for NTFS write support I know about is Topologi-Linux [sourceforge.net], which allows you to run Linux installed in a large loop-mounted file on an NTFS disk (don't need to partition your MS Windows disk to try out Linux, yet get a full "normal" install).

      See http://mlf.linux.rulez.org/mlf/ezaz/ntfsresize.htm l#write for more info on the old vs new NTFS suppo

    • If your VTs are missing (and chances are pretty good that, if you can get into X, you can't start an xterm) you likely forgot to mount the devpts filesystem.

      Try `mount -t devpts devpts /dev/pts` and see if that resolves it; if so, add the appropriate entry to your fstab.

    I've tried three of these, 2.5.74, 2.6.0-test1 and -test2. Every time I boot up the kernel (bzImage from arch/i386/boot) it says "Uncompressing linux... OK " and that's it. Nothing else. I would really love to get this to work out, especially the native ALSA support (my sound card works great under ALSA, not so great under OSS). I'm wondering if perhaps some of the stuff I've compiled in is inhibiting the boot process.

    I have IDE support compiled right in, my CPU is set up correctly (x86/Pentium-II), I'm not using anything fancy like initrd et al, I have ACPI and APM enabled, nss what else I can mention.

    Installed module-init-tools and converted over my old profile (just had two aliases for my network cards), depmod runs w/o any problems (I remembered to pass in the symbols for the new kernel).... argh.

    James A.A. Joyce. I should have been keeping closer track I guess, but I was still trying to do 2.6.0-test1 with the -mm2 and the -int7 patches. Thx for the info, I'll get back to you on it!

    FWIW, I read the kernel ML daily and I can say that the kernel team strongly desires end user feedback in the form of commentary and bug reports (not flames!)

    They're looking for all the possible "oddball" cases (AKA "corner cases") and also for extreme loads such as huge files/filesystems, throughput, mem and net bandwidth, fs integrity, etc.

    Regular users should participate; Linus has said that his focus is still on desktop usability and responsiveness. Anyone else who is interested should make sure to enable the -preempt option as well -- amazing performance!

    Damn... now I need to try -test2.
