This means that scheduler process get the bad mutex, but there may be also other suspect stacks like this?

The related USB dongle is idx 6 with urtwn driver

If I connect the USB Wifi dongle later all works like expected.
The kernel comes from package osnet-incorporation at 0.5.11-2020.0.1.20237
Has the urtwn v0.8.1-oi151a driver some shortcommings? 



Has anyone else seen such problems?
