That seems to have worked. With that parameter added, things work again.
Thank you! How can I prevent the efi storage from filling up? Is there a
way to initiate garbage collection manually?

It does seem to be related as these error messages go away with
efi_no_storage_paranoia. I'm using EFISTUB to boot linux directly from
the EFI shell.
I'm attaching gzipped dmesg output (with efi_no_storage_paranoia).
Thanks again!

Felix
