cpu fan not running in laptop
I've been using debian for a long while then switched to ubuntu on my laptop for suspend to ram support.
This week I decided to give lenny a try and installed it on the laptop. Everything seemed to go fine (except s2ram) but then I noticed that the fan never turned on. I made some tests with cpu intesive tasks and realised it actually never runs. I put on a xubuntu livecd and the fan was back again, when needed.
My laptop is a 2004 acer travelmate290 with a 1.4 centrino and intel 855gm graphics. In 2004 it was running sarge and fan was ok.
I noticed powernowd and was not installed and speedstep-centrino is not loaded at boot, though cpu scaled anyway.
At boot I see a "gpe storm" acpi error. I tried passing acpi_osi="Linux" at boot and the message disappeared though still I have no fan running.
Everything was fine with sarge, ubuntu 8.04 and its livecd but fan is not running in lenny. I think this is a very serious problem since cpu is overheating.
What should I do?
