To resurrect this topic (a sore one for me lately):

On Linux when the AFS mount hangs after a disconnect/reconnect, there is
at least one file server that occasionally never times out.  I believe
this is the source of the problem of the mount perma-hang but don't know
how to debug it further.  If all fileservers time out then everything
goes back to normal.

Interestingly, the gnome-panel also freezes when the AFS mount hangs
despite not (according to lsof or fuser) having any files open in /afs
as far as I can tell.  I wonder if this issue is tied into
inotify/dnotify somehow.
