Hello, calling efibootmgr for adding EFI boot entries with Linux 6.0.8 does not work on our Lenovo T14 Gen 3 (intel). The error is "EFI variables are not supported on this system". The directory /sys/firmware/efi/efivars/ exists but is empty. This worked fine with the latest 5.19 kernel. The config was transferred from 5.19 to 6.0 with "make oldconfig". All kernels are self-compiled and without changes from the kernel.org downloads. I saw earlier messages about bugs in this area, the fixes applied seem to be not complete. Please let me know when additional information would help to debug. Thank you and best regards Ulrich -- Ulrich Gemkow University of Stuttgart Institute of Communication Networks and Computer Engineering (IKR)
