kernel oops in 2.6.12.3 SMP

kernel oops in 2.6.12.3 SMP

[William Park]

I've been having frequent lockup, especially while booting.  Once it
hangs, even reset button doesn't reboot the machine.  I have to turn
on/off the power.  I suspect my memory is going bad.

In the last lockup, some kernel messages showed up in /var/log/syslog.
Can anyone decipher this into plain English?
