NVMe Issue: Unable to change power state from D3cold to D0, device inaccessible

Today it happend again. Looking forward to the help of professionals too.
Hi everyone, for now, I think disable `Pci Express Clock Gating` may be the solution. As I understand it, Pci Express Clock Gating is to turn off the clock signal when the device is idle to save power consumption. Maybe some nvme devices do not support this.
It currently works for me through a simple AB test, I had it running normally for over a month until I rebooted .
you can give it a try
