Ensure you are using the latest BIOS/UEFI. Skylake systems with an old BIOS are unsupportable and broken. This is always the first thing to verify when any Skylake-based system behaves badly when running Debian. You *must* have an up-to-date BIOS with any Skylake-based system to run Debian. Right now, this means you need to check for a new BIOS at least once every two months. Also, ensure you have the intel-microcode package (from non-free) installed. Intel started distributing Skylake microcode updates as well (but they are not useful if your BIOS/UEFI is too outdated). -- "One disk to rule them all, One disk to find them.
