Hi,
In earlier 2.6.30 (rc1 and 2) kernel tests I suffered the "beacon loss,
sending probe request" problem, during which my connection would
intermittently fail and reconnect. With the latest git kernel which
seems to include a patch (ad935687dbe7307f5abd9e3f610a965a287324a9) for
at least some of this, my card (Intel 5300AGN REV=0x24) completely fails
to associate and I get:

I do not have any similar problems with 2.6.29 or 2.6.28 at the exact
same physical location.
I can try to bisect in a day or two if need be.
Regards,
Niel

Okidoki, I've managed to bisect it:
commit 47afbaf5af9454a7a1a64591e20cbfcc27ca67a8
Author: Johannes Berg <johannes@sipsolutions.net>
Date: Tue Apr 7 15:22:28 2009 +0200
mac80211: correct wext transmit power handler
---------
Under normal working circumstances, I get a reported 30-42% signal
strength to my wireless router, with the problematic kernels I just kept
getting probe attempts followed by the timeout, as per my original post.
Regards,
Niel
