I had the same problem on three servers running with an AMD EPYC 7402P 24-Core Processor.
After removing the amd64-microcode 3.20191021.1ubuntu0.18.04.2 package the servers did not end up in a reboot loop anymore and were able to boot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1853614 Title: System stuck in reboot loop on AMD EPYC 7542 32-Core Processor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/amd64-microcode/+bug/1853614/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
