After resume from suspend the NVMe does not wake up again when the
device was put into D3cold. This is something that is worked around by
TUXEDO Tomte[1] via udev rules. However, I personally don't like this
approach and it can lead to race conditions when we're going into
suspend before udev is initialised.
Interestingly, the device does even go into NPSS via APST, but if
changing to D3cold while APST is enabled, the device does not wake up
again.
Right now I just added a new quirk to disable D3cold during device
probe for now, but we could maybe find a better workaround eg. by
disabling APST before D3cold and re-enabling it again. Not sure whether
this is feasible, but since I have limited time right now I can't dig
more into this.
