Update on this - it looks like the NVME drive has a hardware problem of some kind. After making a full clone backup of the non-booting NVME drive, I tried restoring/cloning a known, good backup to it and booting and it would not boot all the way up (black screen). (The known backup is on a...
Looks like we might have opted in to 10.4.6 18G9323 Security Update unintentionally, and 7010 w/NVME won't boot. Errors are
IONvmeController: HandleCompletionErrors( ... )
disk2s1 device error
And gets stuck in a boot cycle repeating this infinitely.
Has anyone else seen issues with this?

It would be great if we could have an OpenCore Big Sur guide for Optiplex 9020 for those who want to engage that build. I wouldn’t jump on it as my Catalina setup is stable but eventually would be interested. Especially if the power mgmt is more stabilized.

sudo kextcache -i /
to rebuild kext caches.
