I tried the last RT patch against a 5.6.10 kernel.

After enabeling the FULL preemption model I'am no longer possible to use 
efibootmgr.

The kernel module efivarfs refuses to load - no device ...


Any idea

Reiner

IIRC, efivarfs functionality is disabled by default due to the patchset.
Add the `efi=runtime` kernel parameter and reboot.

Best,
David
