Hello I am running Suse 7.2, 2.4.4-4GB kernel. The box has a p3tssa mainboard, 815 chipset, pentium 3 processor, 512 M ram. The cards are 3ware(raid),nvidia(video),Yamaha(sound), Linksys(network) The drives are partitioned in ext2 and reiserfs. The problem is that it is unstable. Grepping through /var/log/messages I see lots of Oops messages. A few are attached. I ran memcheck for 24 hours with no errors. So it appears to be a software problem. How can I fix this? Should I upgrade, downgrade, something else? Please offer any advise you may have. I have no idea of what to do.
