passive trip point and raised again after a while) is working as expected:
Is one of these of type "passive"?:
/sys/devices/virtual/thermal/thermal_zone0/trip_point_0_type
/sys/devices/virtual/thermal/thermal_zone0/trip_point_0_temp
/sys/devices/virtual/thermal/thermal_zone1/trip_point_0_type
/sys/devices/virtual/thermal/thermal_zone1/trip_point_0_temp
/sys/devices/virtual/thermal/thermal_zone1/trip_point_1_type
/sys/devices/virtual/thermal/thermal_zone1/trip_point_1_temp
If yes, remember the temperature when frequency should go down
(trip_point_*_temp) and do:
watch -n1 cat /sys/devices/virtual/thermal/thermal_zoneX/temp
/sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq
Does the passive cooling work?
Yes, you should wait and see if the machine shuts down, it should not if this
mechanism works. I remember some ThinkPads were at the very limit and getting
that hot quickly that even with passive cooling they shut down.
You could also monitor the active trip points and watch them. In this case you
should here a fan switching on or getting louder when a thermal zone exceeds
its active trip point.
If both works as expected it may be due some power management features in
graphics driver missing/broken? You could double check whether the extreme
condition only happens with X applications involved or also, if you e.g.
compile a kernel with make -j5, or do:
cat /dev/zero >/dev/null &
several times (this also 100% utilizes CPU cores).
It may also be worth to additionally install kotd from the master branch:
ftp://ftp.suse.com/pub/projects/kernel/kotd/master/x86_64
Best additionally via:
rpm -Uvh kernel-desktop{-base,}.rpm --force
so that you can switch back to the 11.4 kernel and compare.
