Well, reiserfs refuses to pass the filesystem check every time with a queue of depth 8. The one time that I decied to bypass it to look for errors, I got a bunch: http://www.ussg.iu.edu/hypermail/linux/kernel/0307.1/1307.html XFS will boot, but corrupts the fs after a while, and I got an oops there: http://www.ussg.iu.edu/hypermail/linux/kernel/0307.1/2583.html Other than that - no messages. > If it's an ide tcq bug, it isn't very interesting.
