I set new install on old, but SMP server. But when I try to reboot or shotdown, I get kernel panic. Kernel 2.6.31-r10 with config from install-x86-minimal-20100216.iso also have this bug. Reproducible: Sometimes Steps to Reproduce: 1. set rootfs on lvm2 on md 2. try to reboot I try use null modem, but when console on ttyS1 - panic does not reproducing. Never. I had use photo to get dump. When I reboot hard, through SysRq+b - panic does not reproducing. When I boot install CD - panic does not reproducing. ( but then rootfs not on lvm2 on md ) Other time reproducibility is about 90% or even more, but not 100%. Actual Results: When I reboot trough "halt","reboot",CtrlAltDel аfter "Power down." or "Restarting system." I get: invalid TSS: fb6d [#1] SMP last sysfs file: /sys/devices/virtual/block/md2/md/metadata_version When I reboot trough SysRq+o, after "Power down." I get: invalid TSS: fb6d [#1] SMP last sysfs file: /sys/devices/virtual/block/dm-0/uevent screenshots will be later... Expected Results: normal reboot or poweroff I try to debug /etc/init.d/reboot.sh and /etc/init.d/shutdown.sh panic on strings: /sbin/reboot "${opts}" 2>/dev/null /sbin/halt "${opts}" I can use kludge for reboot.sh: add strings echo 1 > /proc/sys/kernel/sysrq echo b > /proc/sysrq-trigger before this line. But I don't have any kludge for shutdown.sh I try to disable hyperthreading in bios - no effect.

I see > 30 patches for the file which has the function disable_io_apic in the git-sources for 2.6.34. Are you able to test 2.6.33 and upon failure, 2.6.34 to see if this issue has been addressed already?

I was test gentoo-sources-2.6.32-r7. It also have this bug. git-sources 2.6.34 will try 10 hours after.

Everthing else, as I see, kept: 1. when console on ttyS1 - no panic. 2. SysRq+O make panic 3. SysRq+B - no panic. Need other screenshots? Or something else?
I found solution, but I don't understand why it work. kernel parameter "acpi=noirq" solve this problem.
Closing as workaournd found
