I am running Fedora 17 on a Frankenstein-like server in my attic (built from bits, some broke, bits replaced). It has run without fault through major upgrades since Fedora 8. It's previous uptime was 157 days. I routinely install the latest kernel updates.
However, the latest kernel update only lasts for 24-48 hours before a kernel panic locks up the machine.
I have never-ever had a kernel panic before. As a temporary measure, I have changed the grub default to a previous kernel version which appears to be fine (current uptime is now 6 days)
I tried looking in the message log for clues about what might be going wrong but there is nothing. I assume a kernel panic just kills the system dead before anything useful can be recorded.
Um...so what should I do next?
EDIT: I'm reasonably certain that emailing Linus and saying "Hey! Your patch broke my server!" isn't the correct response although I sort of considered it simply to see if he'd reply
