Personal recipe when this kind of things happens (generally caused by a
camera switching to power-save mode or that runs out of battery):

 - switch to single user mode
 - unmount everything that can be unmounted
 - remount ro everything that can't be unmounted
 - reboot (and generally enjoy a kernel panic ;-) )

Not suited for critical production servers, but you won't connect a
camera on such a system, would you?

BTW, their are already a couple PR around there:
