Securing Proxmox with Mortar. Issues with kernels >= 5.19

[anim72]

Securing proxmox with mortar works well with kernels no greater than 5.15.
https://github.com/noahbliss/mortar/blob/master/docs/proxmox-install.md

However, for the new hardware configuration I have, kernel >= 5.19 is required. Unfortunately, the boot process hangs with the newer kernels and secure mode enabled.

Boot works fine with the 5.15 kernels in secure mode, only the internal GPU of the 13th gen i7 processor not working, which works well with the new kernels.

My aim would be to make mortar work with the newer kernels. Any idea what can cause this issue?

Were you able to resolve this with Proxmox 7.4, by any chance? It promises to support the updated kernels..

I have done some test and and reported it on Mortar telegram channel last week.
If you install a fresh debian bullseye and upgrade kernel from backports (6.xx), Mortar works if you install systemd-boot and system boots correctly.
But for now we can't install systemd-boot on debian + proxmox because apt wants to remove all proxmox package.

Any more luck? I'm about to start setting this up, was hoping I could maybe mask the proxmox package from being deleted.
