2.6.37-rc2 after KVM shutdown - unregister_netdevice: waiting for vmtst01eth0 to become free. Usage count = 1

[Nikola Ciprich]

Hello,
I just tried running KVM on 2.6.37-rc2 host, and when trying to shutdown guest, it
got to unterruptible state (D) and I'm getting lots of following messages:
[ 1269.392009] unregister_netdevice: waiting for vmtst01eth0 to become free. Usage count = 1
So I just want to report..
n.

Thanks Eric, this indeed fixes the problem..
I noticed the fix didn't make it to 2.6.37-rc2-git3 though,
maybe it just got omited?
anyways, thanks for help!
