I put a new hard drive in the box and tried Fedora 13 and now Fedora 12. It seems to freeze at random or panic. I suspect hardware or a driver. I've been pulling cards, but it seems to happen regardless of what combination I have in the box. I've tried Gnome, KDE, and now init 3, but it seems to happen with the same frequency. I left it on last night and found these messages on the screen this morning:

I don't see any indications of why it freezes in the message log when it does. I looked for core files in a few places but found none.

What experiments could I try that might point to the source of the problem? Would a core file help? If so, how do I get the system to generate one? How do I figure this one out?

Is the panic output the same every time? i.e. is it always the apic timer?
If it is, it sounds like you might have a hardware proplem on the 

By the way, which fedora version have you installed?
If not F13, have you tried F13, and then done a full update?
