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):
Steps to Reproduce:
kernel:[ 2157.199178] unregister_netdevice: waiting for vboxnet1 to become free. Usage count = -2
you need to report vbox problems to the vbox people, as we don't ship that code.
That problem started after I updated kernel through yum.
Vbox was the same.
