[ 0.000000] microcode: microcode updated early to revision 0x5e, date =
2017-04-06
[ 2.621961] microcode: sig=0x906e9, pf=0x20, revision=0x5e
[ 2.622083] microcode: Microcode Update Driver: v2.2.
My system definitely does not have 0x5e by default, the previous microcode
version was 0x48:
[ 2.561730] microcode: sig=0x906e9, pf=0x20, revision=0x48
[ 2.561811] microcode: Microcode Update Driver: v2.2.
The microcode update also resulted in absence of a 'Firmware Bug' message due
to TSC_DEADLINE APIC mode usage:
