Hi,

till I was running on 2.6.34-rc5-mm1 (mmotm) and earlier everything was fine. Now, I'm running 2.6.35-rc6-mm1 (.35-rc5-mm1 was the same) and sometimes when the computer (desktop) returns from S3, the CPU fan is running at full speed making a big noise.

I don't know how to debug that. Bisection is out of question -- it happens once in 10 or 20 cases. There are no fan entries in /sys.

The load is as follows:

$ while :; do cat /proc/loadavg; sleep 3; done
0.37 0.33 0.32 1/325 21358
0.42 0.34 0.32 1/325 21362
0.42 0.34 0.32 1/326 21366
0.38 0.33 0.32 1/330 21386
0.38 0.33 0.32 1/331 21391
0.35 0.33 0.32 1/331 21394
0.32 0.32 0.32 1/331 21397
0.32 0.32 0.32 1/331 21400
0.30 0.32 0.32 1/331 21403
...

I can boot into 34-rc5 to compare that if this is of relevance.

290 kB kernel log since boot over several S3 sleep till now where the fan is noisy:
http://www.fi.muni.cz/~xslaby/sklad/panics/boot.msg-fan_fullspeed

Should you need DSDT, it's there too:
http://www.fi.muni.cz/~xslaby/sklad/panics/DSDT

Any ideas what could have caused this?

thanks,

Just to add, full power cycle is needed to get rid of that. Warm reboot is not enough.

Seems like bios problem... Update bios?

Well, doing 20 suspends in a row from a script should not be too bad.

I don't think so, it had been working for more than 2 years before this issue appeared.

20 is just a guess. I haven't seen it for pretty few days until the day before yesterday. And it looks like CPU1 is brought up a half way. When the fan was at full speed I tried:
echo 0 > /sys/devices/system/cpu/cpu1/online
and whole system freezed. Otherwise this commands succeeds.

I'll load a crash kernel prior turning the CPU off next time.

You can also try to use RTC wakealarm to run suspend/resume in a tight loop.

Well; if it survives warm reboot, then it looks like BIOS problem...

Ok, so this looks like the kernel problem, on the other hand. Two different problems?

Actually, I haven't seen it after an upgrade to the next -mm kernel. Consider it as closed as WORKSFORME for now.
