Huh, good catch.

  Does patch have sense?

Let's see what Ben says. It seems a bit like the
ieee80211_cfg_on_oper_channel() test there should be inverted instead of
removed?

  Could it fixes problems we are talking
  in this thread?

Yes, could be related, also some issue Jouni and Reinette have been
seeing with P2P might be related as well.
Just remembered this old patch, also related to this part:
http://news.gmane.org/find-root.php?message_id=%3c1311607763%2d12603%2d3%2dgit%2dsend%2demail%2deliad%40wizery.com%3e

I thought that patch was going into the kernel.

I'm busy this morning, but I'm hacking on wifi later today if
all goes well, so I can test out this patch.

Thanks,
Ben
