The dmesg in the dump where it starts having issues is often enough to have an idea.

To wrap this thread up, its a hardware problem. memtest fails in SMP mode between 4 & 6G. If I swap in a 4G memory, memtest ran fine for a couple of days. Beyond 4G it fails, memtest itself crashes. Suspect an address line is flaky, perhaps 4-6G is showing up lower in the address space and memtest overwrites itself. (don't know enough about the architecture of DDR4 memory)

Thanks

Ken
