Hi, a. wrong mailing list. Please try linux-kernel@xxxxxxxxxxxxxxx b. Let us know if this failure is new for 5.10.x or not. I.e., did it work previously? c. Is this an x86 system? Probably need to Cc: some relevant maintainers, whether it's x86 or something else. Probably also need to provide more boot log info, not just dmidecode. -- ~Randy
