Thanks , yes, we have our NVMeoF host driver for Windows working nicely.  The IO path is very stable and very fast.  We are seeing issues with disconnects.  When we disconnect se see the problem in the attached log.  Any ideas on what is causing it would be much appreciated.

Are you still doing that Microsoft Windows NVMe fabric host, Linux kernel target solution?

I'd try to see if you can get the mlx5_1 driver working on a Linux NVMe Host, Linux NVMe Target solution first.

Or alternatively use a RoCE v1 NIC+driver on the Windows NVMe fabric host and Linux target.

My concern would be since RoCE v2 is rather new'ish (first appeared in Linux kernel roughly 4.5), there is some interpretation/implementation difference between the two OS's.

But to answer your question, if you are interested in stable
latest+greatest, kernel.org has 4.8.3.  If you want a bit more bleeding
edge, try the mainline kernel at 4.9-rc1 at kernel.org.
