I noticed that you are using CONFIG_CFG80211_INTERNAL_REGDB, but you
have an empty db.txt file.  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?
