It looks like your BIOS doesn'= t=20 include entries for the PCI9 bus in the PIC version of the _PRT (see no PRT= =20 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. =2D-=20 John Baldwin <jhb@FreeBSD.org> =A0<>< =A0http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" =A0=3D =A0http://www.FreeBSD.org
