Dear linux-wireless list,

sorry, I did answer too early, problem still exists. I am now using
compat-wireless-2.6.39-1. I hope, this is new enough (it seems to be
from last night anyway...)

I now even exchanged the wireless card, now I am using a Gigabyte
GN-WI01HT (AR5414 chip), the problem seems to be the same. I attached
some dmesg info. Could this be a hardware error of the mainboard?
Actually, I only have one hardware to test on and I somehow don't really
trust it. Just a thought of mine...

What are your suggestions, or could this really be a bug?

I use the wireless-testing tree, not any compat stuff.  We are
testing ath5k and ath9k currently, and no troubles.

If you can reproduce it using wireless-testing, I'll look
at it closer.  Otherwise, it might be some problem with
the backport.

Thanks,
Ben

Best regards,
Dennis

Hello linux-wireless list!

Is there really no one with an idea? Is there no one among the
developers, who is interested in this bug, if it is a bug?

I'm starting to lose my hope...

Can you reproduce this in the wireless-testing tree?

Ben
