Boot failure on Microsoft Surface Pro 7

[codewizard1975]

Summary

Booting either v4.4 or v4.5 of any edition on Surface Pro 7 direct from a USB thumb drive the system locks up. Using Ventoy, I see a cursor but never get the boot menu to show where Solus can be selected.

Steps to reproduce

Either add ISO images to a Ventoy disk or build a bootable thumb drive.

Expected result

Successful boot into Solus for installation.

Actual result

System freezes before boot menu shows.

Environment

• [ ] Is system up to date?

Think the issue is related to SYSTEMD boot as booting using Grub is fine.

FYI I got a Surface Pro 7 and am currently working on enabling full support for it. You should expect the Surface series and the Surface Pro 7 in particular to be first-class citizens on Solus.

I'll do a longer write-up later but you need to downgrade the UEFI firmware to something before approximately mid-2022 in order to get Solus working on it (for now). This is because of new security measures they implemented that are not fully supported by shim (which is what runs BEFORE systemd-boot) as well as the current version of the linux kernel (though I already have a workaround for that part which will be in the next kernel build).
