[Bug 1934780] Re: shim crashes on Mellanox BF1 SmartNIC

[Alfonso Sanchez-Beato]

Attached logs after "mokutil --set-verbosity true" and resetting state
with "mokutil --reset". In this case the shim was able to load grub, but
then grub failed to verify the kernel:

error: /vmlinuz has invalid signature.
Loading Ram Disk...
error: you need to load the kernel first.
