Please turn-off that option and install a proper CRDA setup. Alternatively, at least give it an up-to-date db.txt file to use for regulatory rules. You are getting a lot of CR_REG1 timeouts from your zd1211rw device. Are you certain that the device is still functioning properly? The zd1211rw driver isn't exactly changing rapidly. I do see that commit e1f12eb6ba6f1e74007eb01ed26fad7c5239d62b touches it. You might try reverting that one? And, of course, you could try to do a git bisect between 3.4 and 3.5-rc4 -- as a Gentoo user, I'm sure you are up to the task! :-) Does any of that move the ball for us? John -- John W. Linville Someday the world will need a hero, and you linville@tuxdriver.com might be all we have. Be ready.
