I have something like that on my Acer laptop (Aspire 5672). Network
drivers (wpi and bge) fails to attach unless I disable acpi.
Unfortunately, acpi is necessary for other important things (thermal
control, cpu speed control) so running without it is not an option.

I have troed a lot of things to fix this (suggested by other people),
but no luck so far.
I think it is due to a bug in bios / acpi.

FWIW, the laptop runs Linux (Ubuntu) without problems:
