Hello,
this is my first reported bug ever, so please be a little bit patient.
I have a Asus V1S Laptop with an Intel 7300 Dual Core CPU
I'm a Suse User and since updating the kernel from Suse 11.1 my laptop suddenly
shut down. In message.log I can read "Critical temperature reached (127C),
shutting down".
So in 2.6.27 I had no problem, I tried the following kernel versions
2.6.31,2.6.32,2.6.33,2.6.34 in different subversions and all showed the problem
Under heavy load (like copying large files, converting raw files..) suddenly
the fan spins up in 2-3 steps to top speed and seconds later the systems shuts
down with the above message.
To narrow down the problem I tried all vanilla versions of the above kernels,
open source nv drivers or proprietary nvidia driver in different versions. None
solved the problem, only the rate of shutdowns varied between kernel versions.
No difference could be found between vanilla or suse kernel or nv vs.
proprietory driver.
After an internet resarch I tried kernel params thermal.nocrt=1 and
thermal.psv=80 on boot without effect. acpi -d showed no change in passive trip
point.
For facilitating bug search I attached the output of
dmesg after boot
grep . /sys/class/thermal/*/*
grep . /proc/acpi/*/*
ls -l /sys/class/thermal/*/*
acpidump
Is anything more needed?
