Bug Description
Binary package hint: atmel-firmware
I have a Atmel usb wlan adapter:
Bus 002 Device 004: ID 069a:0321 Askey Computer Corp. Dynalink WLL013 / Compex WLU11A 802.11b Adapter
which is using the http://
Which has worked well until i upgraded to Feisty Fawn, i am currently on Gutsy Gibbon. The problems have been that the
system freezes when i have been running a cpu intesive program such as a batch job or a open gl game, nexuiz.
I notice something is wrong when the system halts for a 1 second... there could be a couple of halts, then the machine recovers but
after another minute...the system halts completely.
My suspicion is that the at76c503a seems to disconnect during high processor load and reconnected. The result of
a couple of reconnects --> system lock.
If i run the same programs and batch job with a regular network cable attached and the usb adapter unplugged, it all runs smoothly, so
i think it is a driver problem.

I can confirm this one. I have had the 2.6.22-14 kernel. If I use the 64-bit version, my system freezes on startup. My system also freezes when the (USB)adapter tries to connect to my accespoint. Compiling and re-installing the Berlios driver has no effect. Installing the firmware neither. But, on the x86-version, it all works fine, even under a high CPU-usage. I have had crashes in the past, when I had 3 or 4 devede-programs creating simultaniously a dvd, but i don't think this had anything to do with the at76-chipset.
