Things are getting into a really odd state if that particular initial
calibration isn't finishing...

Things I can think of:

* There's some kind of noise going on that's angering the PHY (eg a spur);
* We should be doing a cold reset instead of a warm reset, upon a
channel change; (That fixes some issues I've seen on the AR9280 in
some environments);
* Bad/incorrectly hooked up antenans.

>From a software side, nothing much can be going wrong. as long as the
driver isn't doing something stupid like running multiple copies of
the reset / setup path on different CPUs/threads, it should be
reliable.

HTH,
