Subject: [ath9k-devel] kernel oops
Date: Sat, 23 May 2009 15:42:04 +0300 [thread overview]
Message-ID: <4A17EF1C.1000004@gmail.com> (raw)
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.
