Code: 8b 43 10 8b 40 44 8b 10 85 d2 74 2f b8 00 e0 ff ff 21 e0 ff

Steps to reproduce:

Plug in said USB camera; mount sda1; umount sda1; either disconnect the camera,
eject the CF card or change the camera mode to webcam. Reconnect camera / CF
card or change the mode to 'disk'. Instant and repeatable oops.
