The machine boots and within a few minutes kernel panics. We've tried replacing the memory and trying different memory configurations. The machine doesn't panic while running the Fedora 7 install CD. Version-Release number of selected component (if applicable): kernel-2.6.23.15-80.fc7 How reproducible: Very. Steps to Reproduce: 1. Boot system 2. Wait 3. Additional info: See attached file (gathered using serial cable from crashing system)

Created attachment 297960 [details] another panic in swapper (when doing something) Here's another panic. It seems to have a call trace if it is doing something, but always crashes in swapper.
Created attachment 297961 [details] yet another panic in swapper
Those oops messages point to some kind of serious hardware problem, like bad power supply or memory. The system is jumping to addresses in the middle of an instruction and oopsing on instructions that can't possibly fail the way they do.
Thanks for the comment. It indeed appears to be a hardware fault. It wasn't the memory, motherboard or power supply. After lots of swapping hardware, it turned out to be a bad CPU! I'll close this bug.
