"efi: Failed to lookup EFI memory descriptor" 21.04 error

Asked by BByte

Hi, I upgraded from 20.10 to 21.04 and I found this new error in my logs:

efi: Failed to lookup EFI memory descriptor 0x0000....

 I must say that I'm dual booting, I have secure boot enabled and I always booted in UEFI mode. I don't know if it's a bug, maybe related to the bugged shim that creates problem to older EFI version? Mine is version 2.something so it boots without problems but I don't know.

+1 me too (but I don't have secure boot enabled)

PS that's with EFI 2.7 for me. The boot hangs after this message for 20 secs or so. It then mutters something about giving up on waiting for a suspend/hibernation device and then carries on booting. Perhaps it's the second item, the suspend device bit, that is really the problem?

@BByte try this: sudo update-initramfs -u

This fixed the system hang on boot for me. The EFI fail is still showing but only because I have the splash screen turned off. I am seeing this fail as more of a kernel log advisement than an error.

My mileage variant (?) was that coincident to my 20.10 to 21.04 upgrade I did a system rebuild and changed from swap file to swap partition along with a change from MBR to GPT/LVM/UEFI Lol

I still have the error message in my logs, but everything works fine
