pwmconfig and fancontrol are meant for systems with hardware monitoring chips driven natively by Linux. On laptops everything is under the control of ACPI, so it is completely expected that they did not work.

ok, understod. under kernel 3.7 the fan ran most of the time, so it seems obvious that the notebook never overheated under kernel 3.7. but starting with kernel 3.8 the fan does not run always. so, do i have any possibility to force the fan to run? i found /sys/devices/virtual/thermal and /sys/devices/virtual/thermal/thermal_zone0(12345) but all values there are read-only. is there any way to control/force the fan to run? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I don't know of any way, sorry.

i found out, that i can control the fan, when i do: echo "1" > /sys/devices/virtual/thermal/cooling_device0[123456789101112]/cur_state but not all enabled cooling_devices start the fan to blow... and the strange thing is, that when i do this to /sys/devices/virtual/thermal/cooling_device2,3,4,5,8,9,10,11 the temperature of /sys/devices/virtual/thermal/thermal_zone3 raises immediatelly. shouldn't the enabling of a cooling_device lower the temperature? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

In such a case, try to login in a single user mode with "nomodeset" boot so that no KMS is kicked in, and without GUI. Do you still see the problem?

no. i think, this is because when the system runs in text-only-mode, the notebook doesn't become that hot, so it doesn't reboot.

You could run in text mode and run for example "md5sum /dev/zero" to create artificial load. Then maybe you'd be able to see something before it reboots.

but it seems to be better, after i ran sensors-detect and created /etc/sysconfig/lm_sensors and /usr/lib/systemd/system/lm_sensors.service.

For the record, I can't think of any reason why this would make a difference. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

ok, but if the load produces the reboot, as expected, it doesn't help. it only proves the suspicion. but i will try nevertheless.

These may not all be the same issue, as some users are reporting issues starting with kernel 3.7, which does work for you. Also most of the reports are

yes, i remember that with 3.7 i can confirm that the fan ran the whole time (like many of these other bugs report), which in my case helped, because the notebook didn't overheat. but i think the source of all these bugs is the same. it results in fan running the whole time, or, in my case (apparently with a fix for that whole-time-running-issue) running not at all, or too late to cool the system.

about issues after resume, while your system fails even without a suspend/resume cycle.

yes. but https://bugzilla.kernel.org/show_bug.cgi?id=56281 is also about overheating. in this bug the reporter writes: "If ambient temperatures are above 30 degrees and the computer is slightly used the critical shutdown temperature of 95° for temp1 is frequently reached. This results in an immediate shutdown of the system." this sounds exactly like my problem. the strange thing is, that since i changed the bios setting "fan always on at AC" (which it is strangely NOT) and installung/using /etc/sysconfig/lm_sensors and /usr/lib/systemd/system/lm_sensors.service it didn't happen again. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Can you double check, please.

in the meantime i am at kernel 3.11.4. and as i said in c25 it never happend again. /sys/devices/virtual/thermal/thermal_zone3 has 85° most of the time, and the fan is running most of the time. this is exactly how it was with kernel 3.7. the reboot never happened again. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
