The regression here is that I added a printk() to inform about beacon
loss. The issue has been there a long time, the printk() just exposed
it.

Michael wrote a patch which silences the printk:

http://git.kernel.org/?p=linux/kernel/git/linville/wireless-testing.git;a=commit;h=16eaea5faa37d552b14e246ca56a436e55ca67b3

I fixed the beacon loss detection here:

John, I think Michael's patch should be sent to 2.6.30. Any chances
for that?

Rafael, is it possible to send your regression mails to
linux-wireless@vger.kernel.org as well? Very few wireless developers
have time to follow netdev or lkml.
