The Inspiron 3593 does not have a dedicated Trusted Platform Module (TPM 2.0), but instead the successor Intel® Platform Trust Technology (Intel® PTT). Disabling this PTT in BIOS security settings has *NOT* improved anything.
Workaround #1 does not work for me. Entering 'rmmod tpm' leads to 'command failed', like most of other commands too. For me workaround #2 (unloading tpm module) seems to work. Boot never failed since the last 2 days and around 20 cold and warm reboots. I suspect the root cause in my case was the automatic the update of the grub-efi-amd64-bin from 2.02 (bionic-security) to 2.04 (bionic-updates). I have not yet tried a downgrade of the packages due to limited access to the device. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
