USB device was not fully enabled, only first line: umass0: .. was printed, then if to wait it would have printed that connection stalled. Panic occured between these two messages. This was the second or third time I disconnected camera when panic occured. The first time(s) was no panic. >How-To-Repeat: see above >Fix: N/A >Release-Note: >Audit-Trail: >Unformatted:
