Cool let's get this sorted then.
Here is the output now with the 3.4.6 kernel. If you prefer me to try with the 3.5, I can.
thanks

I'm not sure why you are getting that error -23 (too many open files). Is that
number set artificially low for some reason? What does
cat /proc/sys/fs/file-max
report? On my system, it is 300000.
Attached is a script file that I use to start an AP on my system. Please try it
and see if it works differently. You mnay have to adjust the symbols for
different locations of hostapd, etc, and the address of the wireless network
that is currently set at 192.168.0.X. The script is run with
sudo ./control_ap start <name_of_wireless_iface> <name_of_external_iface>
or
sudo ./control_ap stop
For a normal configuration, the command would be "control_ap start wlan0 eth0".
In addition, one of the attachments in
https://bugzilla.redhat.com/show_bug.cgi?id=797709 is a hostapd configuration
file that works. You might compare it with yours.
