Subject:   Bug? Crash with FBSD 3-3R, fdesc filesystem, tcsh.

OK, this is really weird. I'm running fbsd 3-3 release (not for much
longer; just needed to find the time to upgrade). I've got

fdesc                  /dev            fdesc   rw,union        0 0 

in /etc/fstab. I've got a strange problem which is causing the machine
to hang.

I wanted a look at /dev/sndstat, so I typed:

> cat /dev/sn<tab>

and the machine froze. Odd, but repeatable. No panic message (it's a
tight hang, needs a reset to fix). echo /dev/sn* works fine.

This is with the tcsh port
tcsh 6.06.00 (Cornell) 1995-05-13 (i386-intel-FreeBSD) options 8b,nls,dl,al,rh

It's not a big problem (I don't need /dev/fd generally anyway; umounting
it and the problem goes away). I don't know if this problem is with
4.0-stable too, or actually if this is a known problem (can't connect to
the bug database right now). And since I've got work to do, I don't have
the time to repeatedly crash the machine right now to see what's going
on. So this is all too vague for a problem report; I don't know if
it's a problem with union mounts, the fdesc filesystem, or what. I just
wanted to see if anyone else has the same issue..?

Unfortunately, I have a very good idea how fast my keys are moving.
