ACPI thermal event causes brief freeze

ACPI thermal event causes brief freeze

[Lorenzo Colitti]

Hi,

since I upgraded to kernel 2.6.11-rc4, every time there is a thermal 
event my machine (HP/compaq NC6000) freezes for about 1 second. Audio 
stutters and pretty much everything, including the mouse pointer, stops 
dead for a bit.

This did not happen with a similarly configured vanilla 2.6.9 kernel.

It's pretty irritating. Is there anything I can do to debug this?


Thanks,
Lorenzo

Have you enabled ACPI_DEBUG?
If yes, try again without.

ACPI_DEBUG is incredibly slow since 2.6.11-rc2-bk10.

You probably solve this by not debugging :)

Wow, that seems to work like a charm. Thanks!


Cheers,

it is probably caused by ACPI_DEBUG. I experienced the same - see my mails
from 4th and 14th february with subject "Bad Battery Regresion on Dell D600",
there are some workarounds to this.
