I'm having difficulty getting Linux to work with an R815 that has Opteron 6200 series chips installed. Would like AES and 16 cores per CPU.
Opteron 6100 series chips work fine.
I tried Opteron 6272 and Opteron 6274 chips. During startup get a kernel panic, NMI (Non-Maskable Interrupt) errors, or CPU #27 errors.
I tried the following OSes:
Ubuntu Server 14
Ubuntu Server 16
Ubuntu Desktop 16
CentOS Server 7.2 (Seemed promising until I rebooted.)
On each of these I tried repairing the OS after the reboot failed, but I can't even get back to a command prompt.
I've tried various BIOS options, but nothing seems to be a permanent solution.
