Johannes,
I have discovered that both b43 and b43legacy broke somewhere between 3.7-rc1
and 3.7-rc2. The problem was bisected to commit fe57d9f. The commit message is
commit fe57d9f5c0a2c1ef97ba8cdc42cfda5743f287b8

mac80211: track whether to use channel contexts
Depending on the driver, channel contexts may be used or
not. If they are used, the driver must have support for
hardware scan and remain-on-channel; otherwise the driver
must not advertise support for multiple channels.
Also prohibit WDS type interfaces when channel contexts
are to be used as there's no clear definition of which
channel they use.

It seems likely that the drivers are inadvertently advertising support for
multiple channels, What must be done to turn off this "feature"?
Thanks,
Larry

I hit the same bug with ath9k, and just finished bisecting it when I saw
this thread.
This patch works for me also.
