For instance, Level interrupts from PLX chips on the PCI bus can (read do) generate interrupts when some of the BARS are being configured. Once you get an unhandled interrupt, you are dead because there's nothing to reset the line.
Why not unconditionally clear all interrupts after configuring the chip?
