I have encountered the same error on 2 Epyc servers with Supermicro motherboards running VMware workstation.
The motherboard model is H11SSL-i, CPU Epyc 7301 and the O/S is installed on an Nvme M.2. Booting through UEFI.
Both of the machines are based on Ubuntu 18.04 and the error/reboot was encountered during execution of Windows 7 64bit VMs on the VMWare Workstation.
Have you had any luck in solving the problem ?
I am planning to test the VM on another Epyc server with different CPU & mobo (also Supermicro), based on Centos 7.4
Here is the error log from one of the machines, which is almost identical to your log:
