while trying to shut down my x86 machine (kernel 2.6.31-gentoo-r10) a kernel BUG occurs, I have the framebuffer device installed and can see the whole kernel BUG message. The jist of the message is as follows: kernel BUG at kernel/time/clockevents.c:262 invalid opcode: 0000 [#1] SMP last sysfs file: /sys/devices/pci0000:00/0000:00:1f.1/host0/target0:0:0/0:0:0:0/block/sda/uvent Modules linked in: snd_intel8x0 snd_ac97_codec ac97_bus Pid: 5249, comm: halt Not tainted (2.6.31-gentoo-r10 #4) ... /etc/init.d/shutdown.sh: line 9: 5249 Segmentation fault /sbin/halt "${opts}" the same last line appeared even when I did not have framebuffer, alsa modules, or anything else installed. I have been told that backporting my kernel will solve this issue, but am not comfortable with doing so. this is on an intel pentium 4. Reproducible: Always Steps to Reproduce: 1. login 2. send a command that is supposed to halt the machine (ie. 'poweroff') 3. After Remounting remaining filesystems readonly kernel bug appears Actual Results: Computer does not halt, filesystems not unmounted, often resulting in fsck being run on next boot. Expected Results: The computer is supposed to halt
Who told you to backport what? Please post your .config. What's the last script output before the BUG?
post my .config here, or in a pastebin? also it happens immediately after 'remounting remaining filesystems readonly'

This is reported to be fixed in 2.6.32. Can you upgrade your kernel and test? I've also seen that the kernel parameter nolapic provides a workaround for 2.6.31.
