Boot log from kernel 211 until hang.
Vanilla kernel from git works, I tried: $ git-clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git linux-2.6 $ cd linux-2.6 $ git log | head -1 commit 1bef7dc00caa7bcbff4fdb55e599e2591461fafa $ cp /boot/config-2.6.23-0.211.rc8.git2.fc8 .config $ make oldconfig $ make $ su Password: # make modules_install install # reboot And this kernel starts udev just fine and works. kernel 2.6.23-0.214.rc8.git2.fc8 still broken. Process events/0 is spinning. Can you do sysrq-P multiple times to see where it is stuck? Created attachment 212871 [details]
Boot log from kernel 211, lots of sysrq-P pressed after hang
There is the boot log after pressing lots of sysrq-P. Kernel is always 211.
There is also a sysrq-T just in case the processes are different.
overall it looks very boring to my kernel-illiterate eyes: only ESI, EDI, EBX
and ECX seems to change. ESI and EDI seems to grow together, so I waited for
them to warp around, but nothing happened :-/
Tell me if I can try something else.
kernel 2.6.23-6.fc8.i686 is still broken, but I did a "bisection" downloading from koji all the kernels between kernel-2.6.23-0.195.rc7.git3.fc8.i686 (the last good) and kernel-2.6.23-0.202.rc8.fc8.i686 (the first bad), and I found that kernel-2.6.23-0.197.rc7.git5.fc8.i686 works, while kernel-2.6.23-0.198.rc7.git5.fc8.i686 is broken. The only difference between those kernels is the updated linux-2.6-highres-timers.patch. Sadly the changes between the old version (in 197) and new version (in 198) are big. I will try compiling 198 with the old patch, or without if it doesn't apply. kernel-2.6.23.1-42.fc8 still hangs, But I have some more info: - vanilla 2.6.24-rc1 hangs, while vanilla 2.6.23 works. - a git bisect on vanilla kernel points to commit 4f86d3a8e297205780cca027e974fd5f81064780 as the first bad commit. This is the first commit after v2.6.23! - passing the 'nolapic' parameter fixes the problem for all the hanging kernels. I will try reporting the regression to LKML. That commit is the cpuidle code; Fedora 8 had that before it went into 2.6.24-rc so it makes sense that it is the cause of this problem. I moved this bug to uptream bugzilla: http://bugzilla.kernel.org/show_bug.cgi?id=9355 |
