[ath9k-devel] kernel oops

[ath9k-devel] kernel oops

[Valentin Manea]

Hi,


   I was doing some tests and I got oops below.

   At the time I was downloading some files >2GB data at a high speed 
rate(>2MB/s) and out of a sudden it just started spitting out oops until 
NetworkManager disconnected. I am running the wireless-testing kernel 
cloned today on an Ubuntu 9.04 distro. The net board is an Dlink DWA-547 
and a Dlink DIR-615 WAP both with .11n enabled.
