Comment 6 for bug 2044203

Thanks - yes I understand. This is the first such report that I have seen of problems with these newer microcode versions against this particular CPU - looking at the upstream Intel issue tracker https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/issues I can't see anything similar either. Unfortunately there is not a lot we can do in Ubuntu about this as this package is provided as a binary blob direct from Intel.

Out of interest, can you please ensure you have the latest BIOS updates installed for your machine and see if this helps?

Also you could try reporting this issue upstream directly with Intel to see if they can provide any assistance.
