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.

Could you check the kernel message before reboot via netconsole or such? At least there should be some dying message if it's a "sane" reboot.
i don't think it's a "sane" reboot. i agree with jean's assumption, that it is a kind of "rescue-reboot/-shutoff" to save the hardware from overheating. it happens immediately with no warning. i already checked /var/log/messages for anything, but found nothing. right now, i use the KDE4 desktop-widget for watching the temperatures and/or xsensors. and i see one of the 6 thermal zones which goes higher than the others. it is called "temp1" in xsensors and it is at about 73°C - 81°C. -- 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.
reboot is done in the expected way. But this should leave some record in the log, usually. The fact that it's missing implies that something weird happens instead.
i fear so. the reboot happens suddenly. suddenly the screen goes black and a second later i see the bios-/boot-screen like the notebook was switched on. and there is nothing in /var/log/messages....
In such a case, try to login in a single user mode with "nomodeset" boot option
nomodeset is default "on" on my system. i don't use any KMS driver.
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. it even "survived" a whole night staying idle in KDE4. i just logged in to KDE4 and then did nothing. this seems to produce so less heat, that it doesn't reboot. but when i work with the notebook, it suddenly reboots after a while. 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. -- 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.

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.

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

Question #1: do you hear the fan spin when you force-enable cooling_device2?
when i do this, the first thing, i notice is the raise of the temp of thermal_zone3 from 30°C up to 100°C. (and i didn't let it go higher...) "/sys/devices/virtual/thermalthermal_zone3" corresponds to "temp4" from the output of sensors. the contents of /sys/devices/virtual/thermal/thermal_zone3/device/path is: \_TZ_.TZ5_ /sys/devices/virtual/thermal/thermal_zone3/device/modalias: acpi:LNXTHERM: /sys/devices/virtual/thermal/thermal_zone3/device/hid: LNXTHERM /sys/devices/virtual/thermal/thermal_zone3/trip_point_0_temp: 110000 /sys/devices/virtual/thermal/thermal_zone3/trip_point_0_type: critical immediately after the temp it raising, i hear the fan spin up. when i put "0" to /sys/devices/virtual/thermal/cooling_device2/cur_state the temp is droping and shortly after this, the fan stops. so, it seenms, that changing the value of /sys/devices/virtual/thermal/cooling_device2/cur_state doesn't trigger the fan directly, but raises somehow the temp of /sys/devices/virtual/thermal/thermal_zone3, which triggers the fan to spin up. at least it looks like this.
Question #2: does it prevent the spurious reboot?
i really don't know. the spurious reboot didn't happen since i installed /etc/sysconfig/lm_sensors and /usr/lib/systemd/system/lm_sensors.service. i have the KDE4 hardware monitoring widget running, which shows the temps of all 6 thermal_zones (called temp1 - temp6 in the widget). and i watch the current values the whole time to detect the temp, where it reboots, but it didn't happen since then. but i noticed, that forcing the fan to spin with the above methode (echo "1" > .....cooling_device2/cur_state) lowers the temp of thermal_zone5, starts the fan, BUT raises the temp of thermal_zone3. very strange. and as you can read in https://bugzilla.redhat.com/show_bug.cgi?id=895276 similar things happen with other HP notebooks from other people.... -- 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.

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.

It was fixed in 3.8 and 3.9 some times ago already, and Thomas has just backported it to our 12.3 kernel. Maybe the fix for that bug has its own unexpected side effects that is causing your trouble. Or maybe that bug was masking yet another but and you're only seeing its effects now. It could be interesting to check the behavior of kernel <= 3.6, for example with openSUSE 12.2. Anyway, this isn't my area and I won't be able to fix this bug myself. Just suggesting things to try to narrow the root cause... -- 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.
