[Bug 1937115] Re: Unable to boot/install Impish daily in UEFI boot mode

[Julian Andres Klode]

Seems to be an issue with shim / the UEFI firmware on those machines.
Could be a regression from the load option parsing, but confused as to
how we end up trying to boot a non existing file instead of falling
back.

Could also be memory corruption (shim pull #365).

Need to mokutil --set-verbosity true and record the log during boot with
a camera.

** Package changed: grub2 (Ubuntu) => shim (Ubuntu)

** Changed in: shim (Ubuntu)
       Status: Confirmed => Incomplete
