[Pkg-virtualbox-devel] Bug#677068: virtualbox: Use of vboxnet prevents system shutdown even after virtualbox is exited

[Shai Berger]

Package: virtualbox
Version: 4.1.16-dfsg-1
Severity: normal

Dear Maintainer,

I'm using VirtualBox to run a database server on a "separate system" on
my laptop; thus, I set that system to use vboxnet so my host can
communicate with the guest.

Lately (not sure how long, but consistently), whenever I start this
guest, I run into a problem shutting my (host) system down:
I always shut down the guest machine and exit the VirtualBox control
panel first, and all seems fine. Then I try to shut down my laptop,
but the shutdown process gets stuck, emitting every ~10 seconds the message:

unregister_netdevice: waiting for vboxnet0 to become free. Usage count = -1

At this point, the shutdown has progressed enough that no intervention
seems to be possible (X is long gone, Ctrl-C etc. are ignored; I haven't
tried the SysRq magic -- I know it exists, but not more). I have no choice
but to force the shutdown (long press on the power button).
