The erratum documentation [*] appears to have been updated since last 
week. GNR98 now describes correctly:

   ... Due to this erratum, an Early OS Microcode Update from a microcode
   version earlier than 0x1000405 to a release _after_ 0x1000405 may
   result in a Machine Check Error (MCE).

Chang
