Hi all, I'm having trouble with a fresh proxmox install. I actually have 2 of these devices, I've tried all the below on both with the same results.

HW: Ryzen 7 Mini PC 5700U
BIOS: virtualization set, secure boot off
Proxmox: Tried the 6.4, 7.4 and 8.2 installers

Tried multiple USB drives, and multiple USB creation tools, (dd, rufus, etcher)

Initially had an issue with modprobe failing on `kvm_amd` but added nomodeset to the grub options and got past that.

Now it seems to fail with
`mount: mounting efivarfs on /sys/firmware/efi/efivars failed: Operation not permitted`

There are about 1K entries in dmesg but not sure what to look for.

Any pointers appreciated.

Thanks
