Ah. iommu=soft seems to have done the trick! I can scan now, and I can
see beacons with tcpdump.

However, before every scan I get the following two messages, this
seems to be reproducible every time:

[  206.084438] ath: Failed to stop TX DMA in 100 msec after killing last frame
[  206.084534] ath: Failed to stop TX DMA!

Harmless? Will have to do further testing to see if everything works
nonetheless.

No, should I?

root@xen-debian:~# uname -a
Linux xen-debian 2.6.38-2-amd64 #1 SMP Sun May 8 13:51:57 UTC 2011

Thanks already,
