Ath0 Crash the PC

[Marcos Biscaysaqu]

I have a Atheros card running as Ap in the last version of Freebsd 5.1 
current, with the last Ath drivers files, the problem start when I make 
a simple ftp with more than maybe 5mb the card crash and crash the computer,
the screen say ath0:timeout and i need reset it to make it work again. 
to make it crash doesn't take longer than 2min.

I tried too make a troughput test with ftp traffic in both ways and is 
worse crash after 40 sec
Troughput test logs:
http://202.49.92.224/atheros/TESTFAst.html

my settings:

ifconfig ath0 inet up  ssid mynet media OFDM/54Mbps mode 11a mediaopt 
hostap mediaopt turbo

sysctl net.link.ether.bridge.enable=1
sysctl net.link.ether.bridge_cfg="ath0 rl0"
sysctl net.link.ether.bridge_ipfw=1
sysctl net.inet.ip.forwarding=1

thanks
