So I just got this drive, and it has worked flawlessly in every other system I’ve tried it in, including my ancient Skylake testbench board.
I have an MSI PRO X670-P WIFI, which while otherwise working fine, including with other NVMe drives, is displaying a truly bizarre behavior with this particular drive.
And yes, I’ve just swapped out the CPU with a brand new one and the behavior is unchanged, so this isn’t some CPU PCIe circuitry degradation or something.
When I install this drive, in any M.2 slot on the board, it will work flawlessly for exactly one power cycle. I can reboot, I can hit the reset switch, the drive works just fine.
Until I turn off the machine. After that has been done, the drive will never ever detect ever again. Until I physically remove and reinstall the drive, then it works completely perfectly for exactly one power cycle.
I have a working Linux/SystemRescueCD environment on the machine, so if any PCIe geniuses here have any ideas, I’m all ears.
