That's a good start. Together with your memtest results, it
suggests that your hardware is OK.

Can you confirm that you have either deleted or renamed /boot before
replacing it with files from the CD. An out-of-sync module does sound
the most likely problem. If that doesn't help, please start DDB and
get a backtrace.

Note that memtest cannot prove that your system doesn't have a
problem. There are far too many states that your system could
potentially be in. DRAM is especially susceptable to pattern-
dependent and temporal glitches.

If you're not sure where this is being triggered, you could try
adding 'rc_debug="YES"' to your rc.conf (or even a 'set -x' if
you are getting really desperate). This will make the boot sequence
far more verbose.
