Hi Dell-Robert P,
Thanks for reply.
I have found the reason that raise dpc_watchdog_violation.
The XPS 15 9570 motherboard 's m.2 socket dose not support m.2 NVMe well. I have replaced the INTEL 760p SSDPEKKW010T8 to m.2 sata SSD. It works well.
The m.2 interface of intel _760p_SSDPEKKW010T8 _SSD is m.2 NVMe. See http://www.atpinc.com/Memory-insider/what-is-m.2-M-B-BM-key-socket-3
The XPS 15 9570 motherboard 's m.2 socket should support m.2 SATA and m.2 NVMe.
Why dose XPS 15 9570 motherboard 's m.2 socket support m.2 NVMe with problem? Hardware limitation or firmware's bug? If it is firmware's bug, It may be upgraded to solve this problem.
xps 15 9570 mainborad's m.2 nvme socket support m.2 nvme 3.0; but INTEL 760p SSDPEKKW010T8 m.2 nvme intreface version is 3.1。
So I replace INTEL 760p SSDPEKKW010T8 with SSD that xps 15 9570 mainborad's m.2 nvme socket supported. It work well , never BSOD since I replaced.
