Date: Tue, 10 Aug 2010 13:20:57 +0200 From: Jiri Slaby <jirislaby@...il.com> To: linux-acpi@...r.kernel.org CC: Linux-pm mailing list <linux-pm@...ts.linux-foundation.org>, LKML <linux-kernel@...r.kernel.org> Subject: Fan runs full speed after S3 sometimes (regression) 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, -- js -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
