P44 Pro nvme controller is down will reset

[andy]

NVMe (P44 Pro, model SSDPFKKW020X7) sometimes just disconnects and stops working, smart(attached) reports everything being normal, temperatures are also within reason (around 45-50C, graph of a few minutes before the incident attached). Drive disconnects after about a week or two of uptime (although it was fine for the first month and a half of use). OS is arch linux running kernel version 6.4 (and a few older ones, but this is for the most recent occurrence).

Firmware is on the latest version (checked with the update tool).

I removed the serial number from my smart output (just to be safe), but can send it if needed.

I saw someone with what looks like a related issue (on windows, I assume it's blue-screen-ing due to a spontaneous disconnect): https://community.solidigm.com/t5/solid-state-drives-nand/p44pro-too-hot-to-lose-disk/td-p/24074

Just about 3 months since I replaced my P44 with a Samsung 990. For anyone wondering: I've not had a single reboot or crash since replacing the drive. And this is despite the fact that I've gone through some very heavy usage periods in that time.

Dear oscarfowler,

Thank you for your insights regarding the P44 Pro drives. It's intriguing that different usage patterns and motherboard connections could influence the drive's behavior. Switching the NVMe socket from one connected directly to the CPU to one connected to the chipset, as you did, is a worthwhile experiment to see if it resolves the issue. 

Kind regards,

I can add another report of the same issue:

P44 Pro 2TB, ssdpfkkw020x7
Windows 11
B550 3900xt
The system stops responding and fails to write a crash report to the drive. Upon reboot, the drive no longer shows up in the UEFI.
Need to do a hard power-down and restart to have the drive recognized again.
SMART and temps seem normal.
