What exactly does this mean???

[Jake McHenry <jmchenry oak kcsd k12 pa us>]

I just installed some more memory, and now this is happening when I boot, even
when I try to boot to single user mode.

INIT: PANIC: segmentation violation at 0x2ec54! sleeping for 30 seconds.

It is in a loop of this, and won't stop! I let it sit for 2 hours and it was
still doing the same thing. I didn't touch anything. I shut it down with 

shutdown -F -h now

no big deal. Put in the new memory, powered back on. Bios finds all the memory,
I didn't see if in the boot process it saw it or not, but then this started
happening.

What do I do?

Thanks,
