I'll look around and commit a > real fix later today. I saw you committed something to ata_kauai.c. And in the commit log it sounds to me that the real problem is not solved yet, correct? I built yesterday on my imac and see these errors: ad0: TIMEOUT - READ_DMA retrying (1 retry left) LBA=29430560 ad0: TIMEOUT - READ_DMA retrying (0 retries left) LBA=29430560 ad0: FAILURE - READ_DMA timed out LBA=29430560 I have wired my ata to macio. Thanks, Andreas
