[Bug 1853614] Re: System stuck in reboot loop on AMD EPYC 7542 32-Core Processor
All the comments on this bug mention removing the amd64-microcode package - so it is not clear to me if this worked previously with the older version of amd64-microcode. The security team has prepared updates which revert this to the older version - can anyone who is affected by this please try installing the amd64-microcode package from the ubuntu- security-proposed PPA - https://launchpad.net/~ubuntu-security- proposed/+archive/ubuntu/ppa/+packages - so we can understand if this fixes the issue? -- 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

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
