I don't believe the boot mode should matter.

I have prepared a proposed revert for bionic in the Ubuntu Security Proposed ppa: that downgrades the microcode from 0x2000065 to 0x2000064 for processors with signature 0x00050654. It would be great if you could confirm the version 3.20191115.1ubuntu0.18.04.2 stops the hanging behavior after warm reboots for your systems.

I'm in the process of preparing packages for the rest of the supported Ubuntu releases.

Thanks again.
