Subject: [stable 2.6.24] WARNING: at kernel/time/clockevents.c

Kernel: vanilla 2.6.24 x86_64 SMP
Environment: Debian unstable
Processor: Intel(R) Pentium(R) D CPU 3.20GHz (dual core)

I've been running this kernel without problems since its release, but 
yesterday evening I suddenly got the following error, and this afternoon it 
was repeated (below). The system had been powered down in between.

I have no idea yet what triggers it and am unsure if I'll be able to 
reproduce.
