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?
