It's possible that the GPU issues might be able to affect other things on the
PCIe bus. With Radeon RX 5700 XT I'm also encountering some NVMe-related
errors, but I don't think my NVMe drives have issues as they worked just fine
before I installed this video card.

I recall if I don't power cycle the PC (not just pressing the reset button)
when the freeze happens, one of my non-system NVMe drives would report "frozen
state error detected, reset controller" errors (that the system would attempt
to reset its controller, and it may still work), and some other NVMe drives
might end up being unable to be detected by the system, unless I do a power
cycle (a quick one is enough).
