I've done a bit of digging with this in private, would you (and others
having this problem) please re-test with this patch:
[adrian@pcbsd-3114]/data/freebsd/git/adrianchadd-freebsd/sys/net80211(48)%
git diff .
diff --git a/sys/net80211/ieee80211_power.c b/sys/net80211/ieee80211_power.c

I'd like to see exactly what's going on there; age=0 looks very wrong.
