Bug 4867

Summary: Crash Reading /proc/acpi/thermal_zone/THRM/temperature
Product: ACPI Reporter: Jasper Spaans (jasper)
Component: Power-ThermalAssignee: Konstantin Karasyov (konstantin.karasyov)
Status: CLOSED UNREPRODUCIBLE

Description Jasper Spaans 2005-07-09 09:58:56 UTC 
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.

Steps to reproduce:
Boot, start monitoring tool, wait.
Comment 1 Andrew Morton 2005-07-28 23:56:40 UTC 
Jasper, do you know if this is still happening in 2.6.13-rc3-mm3?

Thanks.
Comment 2 Len Brown 2005-08-04 22:56:05 UTC 
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
Comment 3 Len Brown 2005-08-11 22:18:22 UTC 
any news on 2.6.13-rc6?
Comment 4 Jasper Spaans 2005-08-14 16:04:26 UTC 
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)
