RE: 2.6.0-test4 - lost ACPI

["Brown, Len" <len.brown@intel.com>]

manually modifying ACPI_BLACKLIST_CUTOFF_YEAR and using acpi=force on
the cmdline should have the same effect.

pci=noacpi is also an option.  If it works, then it means you got burnt
by ACPI's PCI interrupt code.  We've had trouble with Award/VIA in this
area recently, so it wouldn't be surprising to have trouble with a
3-year old Award/VIA BIOS.  The puzzling thing is why ACPI enabled
worked for you before and doesn't work now.

I'd be interested in looking over a copy of your /proc/acpi/dsdt, or
even better, the output from acpidmp, which you can get from the pmtools
package here:
