UEFI -l com1,stdio floods console/Windows Server SAC with "rdmsr to register 0x198 on vcpu..."

[Michael Dexter]

Hello all,

Can the "rdmsr to register 0x198 on vcpu..." and similar messages on a 
-l com1,stdio console when using UEFI firmware be redirected or 
suppressed? The -w flag does not silence them, assuming, perhaps 
incorrectly, they are unsupported MSRs.

If redirected, should these be logged?

Thank you!

Michael
