Summary: Kernel panic, hard lockup on cpu when thermal events
occur using kernel 3.2.0-2
Classification: openSUSE
Product: openSUSE 12.1
Version: Final
Platform: x86-64
OS/Version: SuSE Other
Status: NEW
Severity: Critical

Found By: ---
Blocker: ---


User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:9.0.1) Gecko/20100101
Firefox/9.0.1

When a thermal event occurs (when the cpus are under load for some time) I get
a kernel panic - not syncing with the message Watchdog detected hard lockup on
cpu x where x has been 2 4 and 16. I can reproduce this every time the system
is under load and it always results in a trace to intel_thermal.

My system has 2 intel xeon 5670 processors.

Reproducible: Always

Steps to Reproduce:
1.Run a computer intensive process until the cpu fans increase their speed and
the cpus reduce their speed
