If possible, check the cables or try swapping this disk with another. It looks like the problems with ad1 are causing the ata driver to reset the bus as a last resort, and the system is hanging as it tries to swap to ad0 (which is temprarily unavailable due to the bus reset)... That's just a guess. If there isn't anything there, you might try putting this disk on ata1 (secondary master rather than primary slave). It would become ad2 and might avoid killing the entire system when it has problems. For a disk-to-disk backup, it might be a good idea anyway and improve performance (ad0 and ad1 share bandwidth).
