I would assume that the screwed up length information is from the speed at which it was coming out, and possibly another message got throw in at the same time? Yes, it does seem like it was part of one of the other messages. The isp(4) driver was just recently updated in HEAD by mjacob@ who has maintained that driver in the past. He may have some insight if there is an isp(4)-specific problem. -- John Baldwin Heh. Ok, I just watched the same error message scroll across the screen for about 5 minutes now, with a different offset, same length. The fun part is that it is not touching the device, /dev/da1p7 at all. From the systat -vmstat display, I see all of the traffic coming from the /dev/mfid0 drives. It ran for a while, then stopped. So, no access to the drive in question, da1p7, but on the root drive, mfid0. Odd. The partition is mapped to the root drive. I wonder if the driver lost itself, and it tried to access the file on the empty folder on the root drive. Sigh. Anyone? -Trevorhelp
