Hi,
hostapd of 2010-01-08 and compat-wireless of 2009-12-05 are working
together. With compat-wireless of 2010-01-01 hostapd says "Failed to
remove interface (ifidx=0)" and no connection to the ap is possible.
With compat-wireless of 2010-01-05 hostap says nothing while a client
tries to connect.
For the tests today I used kernel 2.6.32.3.
It is hard to biselect the issue, because the AP mode did not worked for
some time on my device.
On an AMD64 System with Ubuntu 9.10 (kernel 2.6.31) and compat-wireless
of 2010-01-07 with the same hostapd version I have no problems.
Here is an other log of the error combined with hostapd debug log with
hostapd 20100108 and compat-wireless 2010-01-07.
