The problem must be triggered by a combination of operations on a directory; I'm certain that if you access inode 24472381 on your filesystem on 2.6.17, that it'll shutdown your filesystem too. See the FAQ entry for a description on how to translate inums to paths, and also the repair -n step to detect any corruption ondisk. cheers. -- Nathan
