Hello,
I've updated my EBVBeagle RevC2 according to the instructions at http://www.angstrom-distribution.org/demo/beagleboard/. When I try to boot the Angstrom demo image, I get the following kernel panic:

The kernel always panics at the same line. The BeagleBoard is powered by an external 5V power source.
Does anyone have an idea on what's going on?
Thanks in advance!
