Subject: ath9k driver in kernel 2.6.33 problems
Content-Type: text/plain; charset=ISO-8859-1

Hi,

I've been trying to use the last couple of 2.6.33 RCs up to rc3-git2 and
am experiencing connection issues with the ath9k driver.  It used to be
broken for me in kernel 2.6.31 (haven't tried earlier), then was
rock-solid in 2.6.32 and now it's broken again.  I can connect to my
300mbit router--which is in the same room--without problems, but after a
while the connection breaks.

Is there anything else I could log?
