From mboxrd@z Thu Jan 1 00:00:00 1970 From: Valentin Manea Date: Sat, 23 May 2009 15:42:04 +0300 Subject: [ath9k-devel] kernel oops Message-ID: <4A17EF1C.1000004@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ath9k-devel@lists.ath9k.org 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.
