Yes, if I remember correctly it worked after I upgraded 15.1 to 15.2 and
installed the nVidia drivers. This caught me by surprise and I was not sure
what to do, so I just selected to continue to boot. The drivers did not load,
but I was able to at least figure out what was happening. I imported the key
again with mokutil and rebooted and selected "enroll MOK".

FYI: I also see via "efibootmgr" that the system seems to be booting
".\efi\opensuse\shim.efi",even though I have SecureBoot disabled (verified by
"mokutil --sb-state"). Note that the firmware bios still says its "enabled",
but this allows the system to boot now.
