I have seen quite a few questions relating to this topic but never any answers so I will try myself. One of the machines I have running FreeBSD is my desktop machine running an Athlon 600 with FIC SD-11 motherboard. I have now tried two different IDE hard disks, I have tried disabling the 32bit transfers and setting the mode down to 0 but with no effect. The problem is that the system reports lots of errors like /kernel: ad0: UDMA ICRC WRITE ERROR blk# 3062797 retrying or /kernel: ad0: UDMA ICRC WRITE ERROR blk#2400383ata0-master: WARNING: WAIT_READY active=ATA_ACTIVE_ATA Then eventually /kernel: falling back to PIO mode This happens from the time of startup until the system falls back to PIO mode. Unfortunately, lately the machine has started locking solid when running X and needs a hard reboot to sort it out - I suspect that if there have been lots of these write errors over time it will screw the file system (technical term!). I have only had to do an fsck manually a few times but don't really want to re-build everything until I know how to sort the disk problem. Is there anyway to force the machine to start up in PIO mode? does anyone know if this might cure the problem?
