Are you sure about that? I've been poking around and it sure looks
like the USB controller is using PCI interrupts.
I couldn't get SRM to print out any numbers in the 9a range, but poking around
in arch/alpha/pci/pci_eb164.c indicates that 0x9a maps to PCI interrupt 10.
USB activity hits eb164_iointr(). I pulled the SCSI board that also
interrupts at 10 and SRM no longer complains. (Unfortunately this
didn't fix my USB problems.)
EB164_MAX_IRQ is 24, so there shouldn't be a shortage?
