Rebooting or shutting down. Before 1.3.81, I would occasionally get
kernel panics at runtime, but no longer; on the other hand, I don't
leave my machine up long enough to necessarily reach that point. I
reboot because AFS starts behaving strangely; I'll get contents of files
that are incorrect, etc. I've used afs flushvolume at least once to fix
that, but I don't know whether it's a consistent fix. In some cases,
I've know that AFS had confused my machine because I'd get a bus error
running gcc; I wish I recalled whether it happened only when compiling
from source files in AFS space, or whether it was any invocation of gcc.
That part isn't particularly reproducible, and I haven't until recently
gotten fed up enough to commit myself to really tracking this problem down.
