Hi,
I am using the latest debian image from http://beagleboard.org/latest-images without any changes. I get a kernel panic when halting the BBB:
Detaching loop devices.
Detaching DM devices.
[ 82.381943] (NULL device *): gadget not registered.
[ 82.394714] Power down.

[ 82.443212] drm_kms_helper: panic occurred, switching back to text console
Any idea?
