I would assume that the screwed= up length information is from the speed at which it was coming out, and po= ssibly 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)-specifi= c 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 -vm= stat display, I see all of the traffic coming from the /dev/mfid0 drives. I= t ran for a while, then stopped. So, no access to the drive in question, da= 1p7, 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? -Trevor=
