I have seen similar messages on adaptec hardware. It was quite mystifying because at first I thought there might be some hardware issues on the system I was trying to resurect and the time required to reproduce the error seemed to be inversely proportional to the amount of disk IO taking place. I ran hardware diagnostics yet they came up clean. I ran seagate's scsi diagnostics (seatools) which you can download for free and they also came up clean. Eventually I was able to track down the documentation for the host adapter and discovered that the scsi bus was not properly terminated on the motherboard. Specifically the wide terminaters should have been removed. I did this, reinstalled the OS and the system ran clean. Note that I had to perform a reinstall... it appeared that some data corruption had crept in. Note also that while I was chasing this issue down I permutated through about 4 or 5 different versions of FreeBSD (4.2 and 4.3) and it seemed some where more sensitive to the issue than others. Hope this helps.
