Hi Mike,

Not sure what that is about.  But it seems harmless for the moment
(please feel free to file a separate bug about it if it causes
problems, or to ask upstream at <http://hostap.epitest.fi/> if
curious).

Hm.  There have been some hostap fixes recently, though they are not
likely to have affected this.  Could you test version 3.0.0-1 from
Debian unstable and if it fails, report it at
<http://hostap.epitest.fi/bugz/>, product "Host AP driver" and send
the bug number to 625953@bugs.debian.org for tracking?

Thanks and hope that helps,
Jonathan
