That was not enough.

3. Updated to buster. Kernel 4.12 is required to make the system stable.
4. It seems that Intel P-State driver is the culprit, though P-State driver is needed while the system is booting. I wrote rc.local so that the CPU clocks do not change after the system boots.

I bought a Core i7-7820x rig. Here are some points for running it with stability.

1. Use Debian. Ubuntu installer does not boot.
2. Turn off Turbo Boost. After Turbo Boost kicks in, the system gets unstable. This is because the new Turbo Boost feature is not supported by kernel 4.9.

The system still fails to boot on rare occasions, but it is stable after booting successfully.
