Description sd.domrep 2012-05-27 05:54:38 EDT
Description of problem:

uname -a:  3.3.6-3.fc16.x86_64 #1 SMP Wed May 16 21:43:01 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

After recent kernel update I start to get this message:

kernel:[ 1585.045043] unregister_netdevice: waiting for vboxnet1 to become free. Usage count = -2

And dmesg got this:

[  903.121037] vboxnetflt: dropped 0 out of 26 packets
[  903.121043] dev_remove_pack: ffff8802100c10d8 not found.

It is impossible to shutdown system properly, because vboxnet device never becomes free.


Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.Install VirtualBox.
2.Start vm
3./etc/init.d/vboxdrv stop

Actual results: 
kernel:[ 2157.199178] unregister_netdevice: waiting for vboxnet1 to become free. Usage count = -2


Expected results:

you need to report vbox problems to the vbox people, as we don't ship that code.

Really?

That problem started after I updated kernel through yum.

Vbox was the same.

Thanks.
