Comment 1 John Kacur 2013-07-22 12:52:45 UTC

what is vboxdrv?

Comment 2 John Kacur 2013-07-26 10:21:05 UTC

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.

Comment 3 Dolan Murvihill 2013-07-28 23:21:13 UTC

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

Comment 4 Darren Hart 2013-07-30 19:30:21 UTC

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.
