Public bug reported:
Since 2.6.30 thermal control does not function after resume: the fan
will not come on until the temperature reaches 80C, and when it does the
fan starts spinning at the highest level and never backs down. This is
tested using Ubuntu 9.10, 10.04 alpha 2 and upstream kernel versions.
Kernels 28 and 29 do work. I suspect the work on thermal in 2.6.30 may
have introduced this regression, but that's a layman's guess.
Steps:
1) Using a kernel version at or higher than .30, suspend the machine.
2) Resume.
Expected: thermal control determines how fast the fan should spin.
Observed: fan stays off until laptop gets very hot, then goes on to full blast.
This machine has an Insyde bios. The DMI info is incorrect (due to some
experimentation with BIOS flashing to see if that was a factor): the
machine is really a Toshiba Satellite L305D-S5881, PSLC8U-00D010.
