BIOS workaround fixes AMD processor bug

It seems that Intel isn't the only one with errata. AMD has released a fix for an erratum that could cause Athlon 64 or Opteron systems to hang. The bug affects the REP MOVS instruction set and can apparently be fixed with a BIOS workaround. Expect to see motherboard manufacturers release BIOS updates that incorporate the fix.
