In the kernel, net80211's state transitions (SCAN -> INIT, ..., INIT
-> INIT) make me wonder, what states is wpa_supplicant in, and what
commands does it send the kernel, at the same time?

FWIW, I have seen APs disassociate clients for several reasons,
including an out-of-order crypto sequence number, or the client's
failure to complete re-keying before the AP timed out (after 200ms,
IIRC).

I do not remember whether you use ral@cardbus, or whether ral uses
hardware crypto, but I have seen drivers do silly things like try to
read/write a crypto register while the Cardbus slot was powered down.
Usually it was harmless.
