Hi
Here's an oops. It could be my fault, because I was playing with vfat, etc., but I didn't have them compiled in when the oops happened. This is with intel UP Linux running on ext2. This oops is repeatable.
BTW, the rename syscall has been failing with ENOENT for files that do exist.

I've got more oopses, but I haven't examined them yet. I may back out all my changes (since I don't have vfat working anyway) and try again.
Thanks!
