I believe I posted it back a week or two ago to the list.  Here's the
previous email:

Now... this may be a tough bug as it has appeared and disappeared with
cvsups dating back well into the summer.  The exact form of the crash
can be different --- which leads me to think that it's some form of
random corruption.

At one point, the crash only happened with a certain sequence of
events, then another cvsup and it would happen for this hub
disconnecting, but not my 4 port, then another cvsup and no crashes,
then another cvsup and the 4 port would cause a crash, etc.

So far, the crashes have been hard and have not allowed a dump to
occur.  Since the machine's almost always in X, DDB hasn't been
helpful, either.
