Having a similar problem with a WDS500G2X0C that I just bought, for an (older) HP Z820 workstation. The HP box is older, so I knew that I was taking a chance. (Updated the BIOS to the latest.) There do seem to be some folk with this model using (other aftermarket) M.2 SDDs.
Bought M.2 PCIe to PCIe adapter: https://www.amazon.com/gp/product/B01N78XZCH/
Linux (Ubuntu 18.04) sees the NVMe device and disk. I can read from the disk (via “dd”) though “only” at 1.4 GB/s. Cannot write to the NVMe disk, either directly via “dd” - which locks up the system) up in attempting to add the disk to LVM (via “pvcreate”).
So … something is not right.
Tried Chris’s grub parameter, but no luck.
Booting off (another WDC) SATA SDD w/o trouble. Want to use the M.2 SDD for fast LVM volumes.
