What were you trying to do?
Test John Kohl's bug report about "fs debug on -dafs 7" not
producing debugging messages as it should have.
What's wrong:
I typed "fs debug on -dafs 7" as myself (not as root). I
didn't get any errors, so I assume it took effect, although it
might not have, because I didn't start getting messages. I
also didn't get any errors, and if it didn't take effect, I
should have gotten an error.
I then typed "ls /afs", and waited for that to finish (several
minutes, of course), and then "ls ~". Right after I typed
"ls~", my kernel panicked with "sleep".

The crash dump is in pit:/site/usr/crash/vm{core,unix}.0.Z.
They are compressed because I don't have enough room on my
site for them otherwise.
What should have happened:
First of all, the fs debug should have worked, but that (of
course) is already in another bug report. Second, the kernel
should not have crashed.
