--- Comment #2 from Christian Sturm <reezer@reezer.org> ---
To give a bit more information:

* Rebuilding the kernel module/port does not help
* This is independent of having the VIMAGE option enabled

Below there is a more complete output. The custom kernel just has VIMAGE
enabled enabled, but is otherwise really close to GENERIC.

This was created with the DEBUG option on emulators/virtualbox-ose-kmod tur=
ned
on.
