you have not provided any info on what kind of machine is this.
i gather this is some sort of a portable machine.
sometimes those have sucha thing as `pci power management', i.e.
changing power mode for pci devices,behaviour you described looks much like
this is what is happening.
if there is no such an option in the bios to turn off the
pci power management and/or turn acpi/apm compatibility
into apm emulation only, then there is not much to do.

except, hmm, maybe, i recall somewone asking me to write
support for acpi, not for 2.9 i would guess though...
