Kernel Panic

[Shauntp]

Hi,

Is it possible to in any way shape or form of code be able to make it so a file runs when a kernel panic happens? I'm hoping for an image (kind of like a mac's kernel panic message).

And, is it possible to edit the kernel panic (im sure it is, just wondering how).

Thanks

When the kernel panics, it means that the system has become so unstable that further operation may irreparably corrupt the system. So, don't even THINK about trying what you suggest! There are log files that should help show what happened, as well as a crash-dump facility you can install to get debuggable kernel images after a panic, LKCD (Linux Kernel Crash Dump). Here is a link to the current version for Intrepid Ibex. A google search on the terms "ubuntu crash dump" will provide you with a bunch of other useful links.

Forgot to mention what the log files are. I think that you will find what you need in /var/log/messages, though to read that file you either need to be root or sudo.
