Panic in i386 6.1.3

[Bob Nestor <rnestor%tx.rr.com@localhost>]

OK, so I jumped the gun on trying 6.1.3 on i386 and amd64 and this may be a 
known issue.  I'm seeing kernel panics on both systems.  Both systems have 
their display, keyboard and mouse connected via KVM switch, so the disconnect 
on wsmouse0 is not unexpected when I switch between systems.  I have the full 
crash dump files, but here's the tail end of dmesg on the i386 panic:
