I can confirm the finding of Terry Kennedy, with the latest snapshot 12-CURRENT
20170309, dd can read and write for a couple of kybtes until a reset is
requested. Further, after the 5 "aborting outstanding i/o messages" (30s
apart), the drive can no longer read / write using dd. Also nvmecontrol reset
seems to have no effect, identify and devlist still work though. 

Here is my exact hardware:
Dell PowerEdge R720
2x Xeon E5-2670 
192 Gb RAM
SM961 on ASUS PCIe x4 to m2 breakout 

I will also try the drive on a desktop tomorrow with the snapshot and report
back.
