Public bug reported: [Impact] This is a regression in shim 15.4 that causes a crash in shim when chainbooting.
Also, the machine resets when you exit grub, rather than going back to the EFI shell when launched from it. [Test plan] TODO for the chainboot, something similar to https://github.com/lxc/lxd/issues/8770 For grub exit, we can easily launch VM and then EFI shell and then load shim from in there, type exit in grub and should be back to EFI shell. [Where problems could occur] In exiting shim, failure to boot, etc. ** Affects: shim (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1931136 Title: Don't unhook ExitBootServices() when EBS protection is disabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1931136/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
