I did an upgrade from my 160Gb drive to a new 500Gb using the new MFSLive, but there apparently is a bad sector on the 160Gb disk that was encountered during the backup and restore/expansion. Turns out it falls in MFS Applications. Despite the transfer error, the new disk booted fine and ran for about 2 hours before giving the GSOD error. I was wondering if the backup alternates of zipper would correct the MFS Applications, essentially overwriting or inserting whatever did not transfer during the upgrade.
