Thermal trouble on 64-bit

Thermal trouble on 64-bit

[Johan Brannlund]

Since I didn't get a reply the first time, I thought I'd try to provide
some more information in the hope that someone will take pity on me.
The thermal control on my AMD Turion HP 6125 laptop doesn't work quite
right. 
The fan often gets "stuck" on whatever speed it had initially and the
temperature readings also often do not change after a few minutes of
running. Doing "rmmod thermal; modprobe thermal" makes the temperature
readings in /etc/acpi/thermal/ start updating again, at least for a few
minutes when I have to repeat the procedure. The kernel is Ubuntu's
2.6.12-6-amd64-k8. Maybe I should mention that I have to boot the
kernel with "noapic" to get it to run at all.

Does anyone know what might be causing this?

- Johan

[Yu, Luming]

Please try 2.6.13-rc6 and option ec_burst=1
The patch at http://bugzilla.kernel.org/show_bug.cgi?id=3851 
could help.

Thanks
Luming

You could also try to set /proc/acpi/thermal_zone/*/polling_frequency
to e.g. 5 seconds.
Maybe it helps?
