what is vboxdrv?
What is vboxdrv? - this is not in the standard kernel. If this isn't an GPL module, we won't be able to help you.
vboxdrv is the VirtualBox Linux Kernel Driver. This is a VirtualBox issue - somewhere, it sleeps while inside a critical region, which is a no-no. See https://www.virtualbox.org/ticket/9748
I think with that we can close this as INVALID. Only VirtualBox can fix this and there appears to be a ticket open on their end.
