[ltp] Critical temperature reached (80°)

[Felix E. Klee]

Recently, I installed Ubuntu 7.10 (Gutsy Gibbon) on my T41, in parallel
to a Slackware 10.2 installation (kernel 2.6.14.4).  There are various
stability issues with Ubuntu yet to be solved.  One of the more annoying
once:

I cannot compile the kernel under Ubuntu, at least not when the
performance governor is used (but the GPU is throttled with "rovclock -c
110 -m 110").  After some time, I always get a message such as the
following and the system shuts down:

  Critical temperature reached (80 C), shutting down.

What may be the reason? Under Ubuntu, I currently am running the default
kernel 2.6.22-14 - does that have issues concerning bad power/fan
management? Or should I better use the on_demand governor?
