Hi Sriram, This and a number of other improvements are in the works around this and other EPYC improvements. This particular issue is a multi-pronged problem of topology which I just finished putting a fix together for yesterday. Should hopefully wrap up a good chunk of this and other stuff over the next week or so and have it upstream in illumos shortly there after. This is https://smartos.org/bugview/OS-7486 and the fix I'm currently testing out is https://cr.joyent.us/#/c/5324/. There's some other stuff I have in the queue to improve the general AMD EPYC support.
