The Intel docs seem to say the same thing. Pulling the drive out generates an ACPI interrupt but not a PCI one. I'm really happy to be wrong here, it's just that everything I've been able to find so far suggests that ACPI is the only way to get a notification that the drive has gone missing :) -- Matthew Garrett | mjg59@srcf.ucam.org
