It just works. Oh, and we have a > hardware watchdog too".... ipmi would be stellar. The shared page change fixed the random lockup and silent reboot problem for me. I've got a 1700X eight core CPU and a Gigabyte X370 Gaming 5. I did have to RMA my CPU (it was an early one) because it had the problem with random segfaults that seemed to be triggered by process migration between CPU cores. I still haven't switched over to using it for package builds because I see more random fallout than on my older package builder. I'm not blaming the hardware for that at this point because I see a lot of the same issues on my older machine, but less frequently. One thing to watch (though it should be less critical with a six core CPU) is VRM cooling. I removed the stupid plastic shroud over the VRM sink on my motherboard so that it gets some more airflow.
