    EPYC 7351 + Supermicro H11-DSi soft reboot blank screen

    sho1sho1sho1

      We have a few Supermicro H11-DSi server with Dual EPYC 7351 and 16 x 8GB DIMMs (Micron 2666).  After running full load (LQCD benchmark) for longer than 5 to 10 minutes, issuing reboot command in CentOS 7.4 will cause the system to go to a blank screen.  The system will not post.  Power cycle will bring the system back to POST everytime.  Without running full load, issuing reboot command works most of the time.  Has anyone encounter this issue?  We are on BIOS 1.0b.  I am just not sure if it's a memory problem or a BIOS problem.

       

      Please help!
