ath5k phy0: gain calibration timeout

Wireless network stopped working after 22 hours with ath5k, I have the
following message repeating, suspending to ram and back was enough to
get it talking again.
ath5k phy0: gain calibration timeout (2462MHz)

I previously was running 3.2-rc5 for a month and a half straight
without any wireless issues, I just upgraded to 3.3-rc1, the message
started 22 hours after booting the newer kernel.  This ath5k is
running hostapd 1:0.7.3-4 with WPA-EAP and had no clients for the 12
hours before the calibration message started, and had no clients for
hours after until I tried to connect and found I couldn't.
While I was unable to connect, I flipped
the laptop rfkill switch and the gain calibration timeouts continued,
disabling rfkill and they still continued.  That's when I did a
suspend to memory and resume and found it recovered.  While it was
working I tried rfkill and it no longer was talking after disabling
rfkill, I thought it was resuming previously, but I don't use that
very often.

I revered the following two comments and will see if I run into any
more problems.  I can test patches.
