Here's the previous email: http://lists.freebsd.org/pipermail/freebsd-current/2004-September/037524.html 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.
