I tried another test. I switched my radio off for less than five seconds,
then on again. I then had to force reassociation manually. I think I hit
the following if-clause:

	if (time_after(jiffies,
		       sta->last_rx + IEEE80211_MONITORING_INTERVAL)) {

in ieee80211_sta.c, with IEEE80211_MONITORING_INTERVAL being 2 * HZ.

I would argue that this is far away from the acceptable behaviour for a
wireless stack. I'm sorry I can't provide a patch, but I really can't read
the code. Using an higher value for IEEE80211_MONITORING_INTERVAL could
result in decreased risks of peptic ulcer, but I don't think this is the
right fix. Any clues? Thanks.
