>Description:
I connected Sony F828 camera (unsupported currently), and disconnected after a stall. Got kernel panic. Even if device is unknown should be no panic whenever you connect/disconnect it.
-- screen messages --
-- first message was
umass0: Sony F828 connected ...(lost here)
-- after a while:
umass0: CBI reset failed, STALLED
umass0: CBI bulk-in stall clear failed, STALLED
umass0: CBI bulk-out stall clear failed, STALLED
-- here I disconnected the camera
Fatal trap 18: integer divide fault while in kernel mode
instruction pointer = 0x8:0xc07c42d3
stack pointer = 0x10:0xe51a17d8
frame pointer = 0x10:0xe51a1860
code segment = base 0x0, limit 0xfffff, type=0x1b

processor eflags = interrupt enabled, resume, IOPL = 0
current process = 44 (swi3:cambio)
trap number = 18
panic: integer divide fault
>How-To-Repeat:
Buy Sony-F828, connect to FreeBSD :)
