I'm having a kernel panic problem - my machine will run for hours, maybe all day and then have a panic attack. I have no idea how to interpret the output, but here's a picture of what's left on the screen when it happens: I've looked through the logs but didn't find anything obvious - I'm still learning though so I've probably missed something. It's a little harder since it's always happened when I've been out or at night so I can't pinpoint the exact time it crashed.

Anyone have advice?

Little late and maybe irrelevant as you don't state what version of ubuntu you are running but you don't happen to have xtables-addons installed on 12.10 do you? I was having a similar problem and tried to resolve it by a process of elimination, removing that package seems to have done it.

It could be that certain parts of your RAM are corrupted. Try running the memtest86+ utility overnight (you can access it when you're starting Ubuntu, on the GRUB stage - if you get no menu, press Esc).

Here's a blog post that describes it: linky

This looks like a kernel bug, so I suggest filing a bug report in LaunchPad against the linux package, attach the image to the bug report. Also, run apport-collect and specify the bug number so the kernel developers can get enough machine specific info to help them fix the bug.

See for more details on how to file a bug.
