WARNING: at /usr/src/packages/BUILD/kernel-default-126.96.36.199/linux-2.6.32/kernel/sched.c:3847 update_cpu_power+0x151/0x160()
---[ end trace 63f382152a7c7034 ]---
As far as we know the issue happens under the following conditions:
- CPU vendor is Intel
- /proc/cpuinfo contains both of the following CPU flags:
- dmesg and/or /var/log/boot.msg does not contain the string
Marking TSC unstable
- kernel flavor is not xen
Only if all four conditions are met the system is affected.
Be aware that this also affect any virtualisation that forward the CPU Flags to the guest (Xen,KVM,VMware)
The freeze/crash can happen anytime after 208 days uptime. It cannot happen before the system reaches 208 days uptime.
Since the issue happens due to an overflow of a CPU register it is strongly recommend to do a cold reboot. A warm reboot might not clear CPU/hardware registers.
A similar issue exists on SUSE Linux Enterprise Server on System z, except that it occurs after 417 days. Please refer to TID 7014192 for details and resolution.
