So I tried on our new Supermicro X11DPU system ( Intel(R) Xeon(R) Gold 6140 CPU @ 2.30GHz ), same issue, hung at boot, but with OS-7079 reverted, it booted up successfully.
I can try NMI tomorrow and update. On Mon, Aug 13, 2018 at 12:06 AM, Jason King <[email protected]> wrote: > Was that with boot -v?
