Also, try this hint with ACPI without APIC.  It looks like your BIOS doesn'=

include entries for the PCI9 bus in the PIC version of the _PRT (see no PRT=

messages in ACPI dmesg) so cbb0 doesn't get an IRQ there either.  I'd be=20
interested in seeing your ASL to see what the _PRT for PCI9 looks like. =20
Looks like this BIOS has only been tested with ACPI + APIC. :(  It has no=20
$PIR, and the MP Table and non-APIC _PRT entries for the PCI9 bus are all=20
busted.
