Default Bug#509613: Kernel OOPS with netdev type devices

Hi Vitaliy,
Hi Debian Team,

the issue is more severe than it seemed. Actually, the kernel crashes
every time the container is restarted. The first start after initial
boot is flawless and the container works nicely.


I'm setting up intermediate start scripts and a container with a
compiler to forge a kernel including the patches. If my family doesn't
kill me within the next days.
