[... etc ...]

Yech.  How does the timing of these messages relate to other events
like the connection being dropped?  Can you start collecting "iw event
-t" output in case it happens again?

The flood of messages seems to have filled the dmesg buffer,
unfortunately.  Do you have a log from the beginning of this storm
(maybe somewhere in /var/log/dmesg*)?  Were there any "gain
calibration timeout" messages this time?

I guess I'd also recommend switching to 3.3 from experimental for now,
even though it is rumored to have similar problems that 3.2.y doesn't
have.  I don't expect it to work better, but it should make it easier
to get help from upstream.
