Hi,
using the latest kernel (Linus master branch) breaks my wireless connection
(ath5k/AR5001), i.e. I'm not able to connect to my WPA-secured AP anymore.
It's been working fine up to (and including) 2.6.34.
Verbose output of wpa_supplicant:

and the whole procedure starts over and over again. I therefore started to
bisect the issue and finally was able to blame commit
6b5d117eddc09cd976ad8030d715f4350f598a22 ("ath5k: clean up queue
manipulation"). After reverting the commit on-top of my branch, everything
works fine again! So please have a look at it and/or revert the commit.
Regards
Toby
