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?

Thanks,
Zhang.Rui(Ray)

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.

Looks we can't use if the device has _PRT to determine if it's a pci
bridge. We'll look at if there is better solution for pci driver.

A Supermicro X7DB8+ does not boot for me -- SCSI driver dies.

Possibly related to this difference -- which by itself is a regression.

I'll send more details when I get a chance to narrow it down.

Neither 2.6.19.1 nor 2.6.19+ACPICA 20061109 show this exception
So either it is transient, or it comes in some later 2.6.20-related patch.
(and the SCSI, hanging off a PCIX AIC79XXX works fine)

The failure is caused by the sysfs branch, which I'll have to drop from the acpi-test tree.
