Some random ideas:
        - reinstall the slower, stable CPUs and burn the BIOS
                If you are a linux hacker then you kept these
                "just in case".. or else
        - get a loaner CPU and use it to burn the BIOS
                If you are a linux hacker then you have no
                life and no friends to get a loaner from but
                you do have a roomfull of computer parts...
                otherwise
        - install only one CPU, it may be more stable
        - run your CPU slower than spec, it may be more stable
                most microcode bugs are not timining sensitive
                but it is worth a try

Good luck.
