This is on Ubuntu 20.04 LTS/focal, correct? If so, this is either exacerbated or triggered entirely because focal's intel-microcode package enabled late loading of microcode (known to be risky) that would get triggered while updating the intel-microcode package itself; see LP: #1883002. Even worse, it would get triggered even if you booted with an earliuer
A regression update for focal's intel-microcode package (3.20200609.0ubuntu0.20.04.2) has been published, https://usn.ubuntu.com/4385-2. Can you test with that version to see if your processor still has problems with the updated 3.20200609.0ubuntu0.20.04.2 version? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1882943 Title: Boot freezes silently after 'intel-microcode' upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1882943/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
