[Bug 1911893] Re: latest microcode is not working properly on intel core i9

[Alex Murray]

intel-microcode is provided as binaries by Intel - other than removing
the particular microcode binary blob from the package which is used by
this particular processor, there is nothing the Ubuntu developers can do
to fix this. I notice on the upstream Intel github project page there is
a comment that they are aware of issues for some CPUs and particular
microcodes https://github.com/intel/Intel-Linux-Processor-Microcode-
Data-Files/issues/31#issuecomment-761228960 - and their suggestion is to
ensure you are running the latest BIOS update for your machine - can you
please make sure you try this first?
