What's causing my Oops MIME-Version: 1.0 Message-Id: <00102702261003.01068@phlegmish.com> Content-Transfer-Encoding: 7BIT Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org I need some help. My system keeps locking up on me or suddenly rebooting. Sometimes I'm able to telnet in and shutdown but usually I have to hit the power button and pray that the disk isn't thrashed. I'm running RedHat 7 and it happens with the supplied kernel or with a new kernel. I'm currently running linux-2.4.0-test8 right now and it is compiled using kgcc. (Found that tip in a message here) I searched through my logs for help and find lots of these Oops messages. I then did some searching on what Oops is. I was told to run ksymoops to get more info but this extra info is way over my head. I'm posting this here in the hopes that somebody can help me pin down what module or kernel setting is causing all my problems. Thanks for any help.
