I've found the following in logs, can't tell when it really happened and
what caused it:

BUG: warning at kernel/cpu.c:51/unlock_cpu_hotplug()

System is still running, so it's not that serious, but still annoying.
I've searched a bit and found a patch, that might fix this, it's
applied in current Linus tree:
