Good news: It also works again in my home machine, so showing it one
time to the windows driver made it work again. (Hm, I remember lending my
2835 to a windows guy once.)

Bad news:
Redstar:/usr/src/prism54# rmmod prism54
Warning: kfree_skb passed an skb still on a list (from d5d10a20).

Not being able to unload the driver module makes it very hard to keep
quick turnaround times. Reboots are very annoying.

Is there a patch or how I can track this down further?

TIA,
