I looked into this a few months ago for slightly different reasons (juju/maas getting confused and not identifying a disk, due to differing kernels used for install vs boot), I can confirm I found at the time that the nvme by-id symlinks change due to backporting of the NVME_QUIRK_BOGUS_NID quirk. This was
Unfortunately backports of this quirk for random SSD models has been regularly done to linux -stable kernels upstream. I ran out of time to follow-up on this at the time, but probably this practice needs to be raised upstream with the kernel and possibly needs to stop and/or some solution to do with the symlinks needs to happen, I didn't quite get as far as understanding why the BOGUS NID matters and what that breaks, or what is fixed by the change, fully. There are a couple of other open bugs related to this issue, e.g. where it also breaks on upgrade: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/2039108 https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1940723 in my juju/maas case this was happening with VirtIO SCSI devices too, not a real SSD. As that was also quirked. May make for a way to reproduce the issue without one of the effected SSDs.
