awokd, could you please answer some questions:
1) From where you got that 0x06001119 microcode patch?
Is it a trusted source of a microcode? (hope its directly from AMD)
2) Is there any way to determine that 0x06001119 is really the latest microcode?
Or there could be more recent versions available?
