Hey guys,
  I'm having trouble with the MOESI_hammer protocol losing interrupts for
the IDE device in x86 full-system.  The following message is printed to the
system.pc.com_1.terminal:

"
hda: dma_timer_expiry: DMA status (0x64)
hda: DMA interrupt recovery
hda: lost interrupt
"

  Many of my simulations are still completing correctly.  However, I'm
concerned because this lost interrupt appears to insert a bubble of a
couple simulated seconds into the runtime of my benchmarks, presumably
while the operating system tries to reclaim the lost interrupt.

  Anyone have pointers for how I might go about tracking this down?
  Thanks,
  Joel
