an update on this:

it was actually pcie_aspm=off what helped to solve the problem.

I think the problem is related to the power management of PCIe ports.

Without pcie_aspm=off I started seeing errors like the following ones:

- [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A (start=7841 end=7842) time 291 us, min 1063, max 1079, scanline start 1044, end 1092

 pcieport 0000:00:1d.0: AER: Corrected error received: 0000:00:1d.0
 pcieport 0000:00:1d.0: AER: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID)
 pcieport 0000:00:1d.0: AER: device [8086:a330] error status/mask=00000001/00002000

I think the bug is not with the nvme controller but somewhere in ASPM. But I am not a kernel developer.
