Not sure if this was effected by the upgrade but after I upgraded to 6.12.8 two out of my 4 NVME drives appear not to be recognized. All 4 of my NVME drives are mounted through an expansion PCIe card. Both drives that are missing are WD_BLACK_SN770_2TB drives. When I checked the card I can see all 4 lights are enabled to the expansion card, so it appears that they have power to them, but I don't know that if they are completely hosed and need replaced or if there is something else that cause them to go offline after the upgrade:
Feb 20 09:47:57 Tower kernel: nvme nvme0: Device not ready; aborting initialisation, CSTS=0x0
Feb 20 09:47:57 Tower kernel: nvme nvme0: Removing after probe failure status: -19
Feb 20 09:47:57 Tower kernel: nvme nvme1: Device not ready; aborting initialisation, CSTS=0x0
Feb 20 09:47:57 Tower kernel: nvme nvme1: Removing after probe failure status: -19
If anyone has any insight, that would be helpful. I just find it strange that two drives would completely bork out after an OS upgrade and reboot. I have a downloaded diagnostics report, but there's quite a bit of files in there, so I'm not sure which one to post up if anyone wanted to take a deeper dive. TIA!
