    Could someone please tell me what the possible cause was for this kernel panic? Happened right at startup. This is a fresh install of 10.6.8 with no programs added.

    When restarted it only registered 1gb of ram. I reset the risers and the ram. Everything seems to be fine now.

    Ran extended hardware test and found no problems.
