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

    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, Rogério.
