I am still having problems after applying the backported patched driver.

I went from my wifi dropping out ~ every 20 minutes (reason 2) with a
reboot being the only way to reestablish a  connection to this:

I suppose it is an improvement in that the need to reboot is gone. But the end result is that every few minutes there will be a period where the connection cuts out completely or latency goes WAY UP as network manager tries to reestablish the connection.
