Thanks. This is peculiar, but indeed pretty clear on the issue being
triggered by use of nl80211 instead of WEXT regardless of what the
actual issue is. I haven't used wpa_supplicant v1.0-rc3 pretty much
at all myself and there has been quite a few changes in nl80211
interaction since then. Anyway, this should give a good test case with
the current kernel and that somewhat older version with nl80211
implementation in wpa_supplicant.

If you'll get a chance to do that, it would be quite helpful since it
could make it easier to try to reproduce this if there is indeed
something special about that AP behavior that allows the issue to show
up but does not show up in the wpa_supplicant debug log.
