@ppedemon Well, I'm the OP so WORKAROUND 2 does work for me (obviously). I deployed these laptops with it after testing that it was stable so I don't have access to them anymore. I did look into the git history of grub and it seems to be related to some patches around TPM where it fails to perform some sort of tracing if the tpm chip isn't happy. This happens regardless of whether you've installed using secure boot or not. Anyway, It wasn't happening for me on 18.
I had a forum posting here https://ubuntuforums.org/showthread.php?t=2445531 where oldfred got me on the right track. I tried to include all the information in this bug report though. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883785 Title: intermittent boot failure dell inspiron 3593 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1883785/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
