The virtual box drivers are a huge mess. Seriously, I really don't even
know how the things are able to work at all (virtual table pointers from
userspace through to the kernel?) I spent a bunch of time to try to
clean them up and get them into mergable state, but without the ability
to also fix up the userspace side, that ended up being a dead-end.

Can you duplicate the problem without these modules loaded? I'd blame
them for any problems you might ever have, given how crazy they are.

thanks,
