I finally got a little time to try to search for which package exactly causes this problem.
I downloaded: intel-microcode_3.20151106.1_amd64.deb intel-microcode_3.20190618.0ubuntu0.16.04.1_amd64.deb intel-microcode_3.20191112-0ubuntu0.16.04.2_amd64.deb intel-microcode_3.20191115.1ubuntu0.16.04.1_amd64.deb intel-microcode_3.20191115.1ubuntu0.16.04.2_amd64.deb I had downgraded to 3.20151106.1, which is working. So, I tried intel-microcode_3.20190618.0ubuntu0.16.04.1_amd64.deb, and it worked ok. So, next I tried intel-microcode_3.20191112-0ubuntu0.16.04.2_amd64.deb, and it worked ok. So, Next I tried intel-microcode_3.20191115.1ubuntu0.16.04.1_amd64.deb and it hangs on warm reboot. So, next I tried intel-microcode_3.20191112-0ubuntu0.16.04.2_amd64.deb, and NOW IT hangs on warm reboot. So, next I tried intel-microcode_3.20190618.0ubuntu0.16.04.1_amd64.deb, and now IT TOO hangs on warm reboot. So, Next I tried intel-microcode_3.20151106.1_amd64.deb, and it works ok -- Unfortunately, I just don't have time to go back one by one through all the releases between 3.20151106.1 and 3.20190618.0 to see how far back I need to go before finding where it really would start working ok again. I find it very puzzling that the packages all worked until I got to 3.20191115.1ubuntu0.16.04.1, and then none of them worked until I backed off all the way to 3.20151106.1. There must be a clue in that somewhere. Good luck, I hope you find it -- I'm staying locked on 3.20151106.1 until this gets fixed...
