Hello.
Post-installation of the RT kernel, i’m unable to mount. load or find efivarfs. And because of this I’m unable to use efibootmgr.
Everything works as expected when running the normal/generic kernel, 5.15.12-1, on the same system.
For both kernels, generic and RT, the following produces exactly the same output -
zcat /proc/config.gz | grep -i efi
Any advice would be much appreciated.
Thanks.
Have you testet to boot in UEFI-mode ?
When booting in legacy mode (BIOS) the evi variables are not accessible.

Hi.
Thanks for the reply.
Yes, I checked that I was booting into UEFI, multiple times, before posting.
I disabled legacy boot in BIOS to ensure I’m only booting in UEFI mode. I also don’t have a boot partition, only a EFI partition. Also, when I boot into the normal kernel via the same GRUB menu, I have access to efivarfs.
Also, the top lines in my dmesg log -
