Yes. We do made several changes on .bind/.unbind method. It seems that DEVICE(BPD0) doesn't have the _PRT method, which is required when binding BPD0.PXH0 and BPD0.PXH1. This is really strange... Len, can you show me the ACPIDUMP and dmesg of 2.6.20-rc1 with this debug patch please?

I think the failure comes down to the sysfs branch not finding the PRT that is necessary to configure the SCSI controller on the PCI-X bus, and the SCSI boot disk subsequently loses its mind. < ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.P0P2._PRT] < ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.P0P2.BMD0._PRT] < ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.P0P2.BMD0.BPD0.PXH0._PRT] < ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.P0P2.BMD0.BPD0.PXH1._PRT] < ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.P0P2.BMD0.BPD2._PRT] < ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.P0P2.BMF3._PRT] < ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.P0P4._PRT] < ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.P0P6._PRT] < ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.PEX0._PRT] < ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.PCIB._PRT] 268a316,325 > ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.P0P2._PRT] > ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.P0P2.BMD0._PRT] > ACPI Exception (pci_bind-0153): AE_NOT_FOUND, Invalid ACPI-PCI context for parent device BPD0 [20060707] > ACPI Exception (pci_bind-0153): AE_NOT_FOUND, Invalid ACPI-PCI context for parent device BPD0 [20060707] > ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.P0P2.BMD0.BPD2._PRT] > ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.P0P2.BMF3._PRT] > ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.P0P4._PRT] > ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.P0P6._PRT] > ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.PEX0._PRT] > ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.PCIB._PRT] dmesg for 2.6.20-rc1 success and 2.6.20-rc1-sysfs failure attached. -Len
