This is brand-new btrfs / system, after formatting and OS installation.
Recently today, I have been running memtest86 for almost six hours. It passed
tests five times without errors. I've also updated PC BIOS to the latest vendor
recommended version to overcome possible issues with Kaby-Lake and HT. So, I am
sure that hardware part is fine.
