Thanks, I had both options enabled. Disabling these makes the 
kernel to boot again. But I just run into another bug:

[17180751.908653] BUG: unable to handle kernel NULL pointer dereference at 0000000000000008
[17180751.911775] IP: [<ffffffff803dff37>] start_xmit+0x41/0x11a


Going to support with debugging support now to get a better backtrace.


Thanks,
Bernd
