Hi! The last weeks I had the problem, that my NVMEs (Samsung 990 Pro) where suddenly disappearing on a Supermicro H13SAE-MF mainboard:
> Unable to change power state from D3cold to D0, device inaccessible > [...] > Disk failure on nvme0n1p3, disabling device. > ...] md/raid1:md0: Disk failure on nvme0n1p1, disabling device. > [...] md/raid1:md0: Operation continuing on 1 devices. It turned out later, that many people, using different mainboards and CPUs and operating systems, reported the same problem: https://www.reddit.com/r/buildapc/comments/1hpmia0/samsung_ssd_990_pro_in_raid_1_on_servers_disks/ I also had kernel panics when I rebooted the server with following error messages: > [...] ? do_wp_page+... > [...] ? srso_alias_return_thunk+... > [...] ? __handle_mm_fault+... > [...] ? srso_alias_return_thunk+... > [...] ? handle_mm_fault+... > [...] ? srso_alias_return_thunk+... > [...] ? do_user_addr_fault+... > ... > [...] ? exit to user mode prepare+... I then changed the Samsung NVMEs with Micron 7400 Pro NVMEs. But I still had the kernel panics after reboot. Since yesterday, after Debian 12.9 was released (https://www.debian.org/News/2025/20250111) I've been restarting and restarting the server, but had no more kernel panics. I wonder if you are aware of an issue and if this new release fixed it? -- Kaulkwappe
