So I thought. But I had also enabled EFI_STUB because the Debian kernel had it, but it causes "failed to unprotect memory range at..." messages. Thus now after kernel upgrade to 7.2.13 I disabled it -> can't boot. Setting this is needed with BIOS v4.23: CONFIG_EFI_STUB=y CONFIG_EFI_HANDOVER_PROTOCOL=y (maybe, =n not tested) Johannes
