I'm seeing this all the time with ath9k.  For now I'm running with the
following local hack:

which makes the problem of an actual disassociation after this message
go away which made wireless completely unuseable with -rc3 for.  Given
that the message never appears a second time just increasing the time
it appears that just increasing IEEE80211_MONITORING_INTERVAL should
fix the problem, too.
