Well I can't say for 100% sure it wasn't on 6.13.7, but only that on the
periods of time I've tested it didn't happen.

Also on the limited amount of time, that's right, it didn't happen at all
during such circumstances (webcam on a separate bus); I didn't test webcam on
same bus, but connected directly on the bus (without the monitor hub); my
feeling is that the monitor hub is somehow the issue; I could focus on testing
that aspect.

I also tested with the bootargs, this is the result:

```
