What if the failing PCI access happened in an interrupt routine? (I'm thinking of the situation where you may need to read the PCI status registers to find out whether an error occurred.)
Also, for that matter, what if a network device receives an abort while performing BM-DMA?
Do we even care about either of these two scenarios?
