PCIe trouble with 4TB Crucial T500 NVMe SSD for >1 power cycle on MSI PRO X670-P

I have a similar problem with a Jetson board. If I turn off the power long enough (one night) and then turn it on, the only PCI card is not recognized and I have to power-cycle it to get it running.

Mind sharing what board/Jetson module you've seen this on? I've seen this exact symptom very intermittently on a custom board and we've wondered for a long time if was an issue with a specific type of module (or manufacturing lot of modules).

My startup logic now power-cycles it until the PCI board is recognized; it works, but it's not a great solution.

Interesting, we're using a completely different module (Xavier NX). And the same, disgustingly hacky, fix, of forcing a reset until it works.

I also run these commands:

    echo 1 > /sys/bus/pci/rescan
    sleep 1

Sometimes it brings the PCI card back, so I just run this as part of my boot sequence.
