Bug Description

Binary package hint: linux-image-2.6.28-11-generic

Hi!

After an Intrepid => Jaunty upgrade this weekend, my HP 2050eg laptop started to reach critical temperature often.

This happened during normal operation, but for reproducing the problem, I've used cpuburn/burnK7 to provoke the problem.

The attached script starts two instances of burnK7, and keeps monitoring the system temperature.

2.6.27-11
2.6.27-14 both survived for quite some time without problems. (the 2.6.27-14 logs are fewer because it was the first kernel I tested)

2.6.28-11 kernel shutdowns under one minute from starting the burnK7 processes.
2.6.28-11 with powersave/800MHz locked in seems to be able to survive the burning too.

Thanks,

Andreas
