Distribution: Debian/testing Hardware Environment: Shuttle AK-32 motherboard, Athlon XP 2000 Software Environment: 2.6.13-rc2-mm1, which contains ACPI: Subsystem revision 20050408 Problem Description: I run a home-built daemon on this machine to monitor the temperature, and if necessary to start throttling the processor. After upgrading to 2.6.13-rc2-mm1 this daemon causes a fatal oops. Note that this behaviour only occurs after some hours have passed.

Jasper, do you know if this is still happening in 2.6.13-rc3-mm3? Thanks.
Jasper, Can you clarify which kernels work and which fail? You mentioned that upgrading to 2.6.13-rc2-mm1/20050408 fails. What did you upgrade from that worked? How about vanilla 2.6.12 or vanilla 2.6.13(-rc6, when that arrives)? Ie. is this specific to -mm or does it happen in Linus' tree too? Can you attach the source for the daemon so that Konstantin can try to reproduce the failure? thanks, -Len
any news on 2.6.13-rc6?
Well, as to testing newer kernelversions, the cpu-fan on the processor on the motherboard with these symptoms failed -- unfortunately taking the cpu with it. I've replaced it with a new one, and cannot test the old one right now. (If I can get hold of an ancient athlon, I'll try to do some testing)
