I have tested on the server  with the latest wireless-testing the past days 
(2.6.28-rc9-wl). The wireless-testing looks somewhat more stable then the 
compat-wireless. 

I have also installed the netconsole module to watch any kernel prints. After 
running hostapd (v0.6.6) from command line the AP is up-and-running. Then if I 
connect with the laptop (tested it with kernel .26 and .28 on the laptop) I 
get a connection and can start a browser en explore the internet. If I start 
a second session (Kmail or second browser) the 
server hangs within a minute. Leaving again no trace on the console, 
hostapd-log or netconsole.
Only way to reset the server is switch off the power.
Its very frustrating because no information or what so ever can be found.

If I connect an internet radio (Musicpal) to the server there is no problem. 
It stays stable for hours. If I also connect the laptop and start a browser 
the server hangs again within minuts.

Its looks like if there is a second connection been set up the server hangs.

Anyone any clue how to investigate this??

Thanks,
Willem
