Upgraded to 3.18.6, built the kernel with static squashfs, and now it doesn't panic anymore. Guess some fixes for 3.18.6 fixed this too. If somebody really, really cares, I could go through the whole procedure again with 3.18.6, but I guess, as it's gone now, this would be rather academeic. Bye Tim
