This is on a kernel from May 2. The machine is an nfs client that had filled up
the nfs mounted drive it was working on. At the time the drive filled up I was
running the ACE tests (that's what filled the drive up), but I don't know if the
actual tests themselves had anything to do with it.

I'll leave the console connected for the next few days, so I can get further
debugging data if anyone should need it.
