Thanks for the follow-up and extra info, I have 3700s running on x86/64 Ubuntu 14.04 and working fine.
I did update the drivers from the Intel site even though they were already in the 14.04 kernel when I was troubel shooting something else.
What happens if you do a dd if=/dev/null of=/dev/nvme0n1 bs=512 count=1000000 conv=notrunc

I am running this on Linux (Ubuntu/3.12) and I am accessing the raw device (/dev/nvme1).
I have tried accessing with dd, nvme-cli and fio Thx Kishore
