Actually that's the back end of a LBA I/O cycle generation (this is the actual read that guarantees completion semantics---see lba_pci.c). The HPMC occurred because port 0x1008 timed out on an outl, I think. That's tulip register CSR1 (i.e. the tulip driver was trying to force an immediate transmit). I assume this must be either because the tulip failed to respond to the outl in time or because the Astro couldn't get on the bus in time.
