attached. the cameras were plugged in but not being used. the
ethernet adapter drives a local network with alot of video recording
going on, about 100Mbit, but two minutes into reboot i don't think it
was recording yet.

i recall now that the shutdown wasn't normal. the video playback hung
with a black screen. i know from experience the cleanest way to proceed
is alt-sysrq-e which starts everything running again and X11/gnome
restarts. but i know things won't be right after alt-sysrq-e and so i
switch to a console and ctl-alt-del. this shuts down cleanly. i do use
the nvidia proprietary drivers.
i checked if the messages appeared during shutdown and they did not.
this appears in the logs immediately before the flood (sorry i missed
it the first time)
