Date: Mon, 10 Aug 2009 22:26:53 +0200 From: Matthias Dahl <ml_kernel@...tal-soul.de> To: linux-kernel@...r.kernel.org Subject: Oops w/ 2.6.31-rc5-git5 Hi. I gave 2.6.31-rc5-git5 a whirl today for various reasons and ran into the following oops two times which both resulted in file corruption w/ ext4 (files getting mixed together) because the system crashed or behaved erratic and required some magic work. Both times, I had a few compile jobs running in the background and KDE 4.3 in the foreground with a widget that polls the CPU core temperatures.
