Are you using networkmanager or systemd or even both ?
Atleast at some point networkmanager have had problems when trying to
activate wireless faster than the hw like, so you get into
auth/deauth loop, and for every time interface restart gets detected,
setting crda gets triggered.

For me systemd also has had the same problems for me from time to time,
and the only way to get wireless up then is to disable it for a
~5+ seconds with the hw killswitch, and when I re-enable it, network
comes up as intended.

This happends for me with atleast 3.0 and 3.1 kernels and Intel 4965AGN
wireless connecting to a 11N 5GHz AP.
