Unfortunately, I have already tried that and I still get stack traces like
this one (this time, booted without any acpi-related option):

Disabling IRQ #10

I can provide any information that is necessary about my system to fix the
problem.

I just finished compiling kernel 2.6.11-rc3-mm2 and I will report back if
there is any difference.


Thank you very much for any help, Rog?rio.
