Re: dpc_watchdog_violation after upgrade

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.

Re: dpc_watchdog_violation after upgrade

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.
