Hi Andrew,

I too thought bad hardware. I will try removing the extra 64M I added
recently and see if it still happens.

After a crash I say Y (within 5 seconds) on reboot to run an fsck and there
are usually corrupted files from what I was doing when it crashed. Eg I was
running rpm -Uvh kernel-sources... and some files in /usr/src/linux... were
corrupted.

How do I do this when the box has crashed? I can manually write down the
oops, but then what do I do? Can I manually look up System.map to get what
you need?

I agree. Everything is pointing to the new memory, even though I
successfully ran memtest86 for 10 hours.

Thanks
