If you can reproduce this without the horrid vboxdrv kernel modules, please let us know, otherwise you are going to have to ask the virtual box developers, as there's nothing we can do if their code is loaded in the kernel (and their code is really really really horrid, seriously, I don't even understand how it is semi-stable at all, it's the stuff of nightmares and there's good reasons why it is not included in the upstream kernel releases.)
