Hi,

I did not find the time to further investigate this issue. Well what I
did today was compile the latest git-update and the latest hostapd. At
least the machine does not crash that often, but with 802.11n I can't
connect to the card ... but this might also be a problem with the card
in my laptop. I hope I'll find the time to go on testing next week.

Best regards
Jens
