Hi.

Today I was testing Again the ATH card with the same motherboard but  
in FreeBSD 7.0.

I get exactly the same problem of the irq storm but at least I can use  
the card after change :

sysctl hw.intr_storm_threshold=10000 ( or more)

But if you try to do anything with the wireless card the console or  
ssh or telnet hang up until the transmission is finish, after you  
finish playing with the wireless card everything is back to normal, so  
definitely a high storm_threshold is not the solution.

I will try the same wireless card in a Acer Laptop with freebsd 7.0  
and 8 and I will update the results.

We want to use FreeBSD for more than 100 Radios, so this could be a  
enormous Live-Lab :)

Thanks in advance.
