Q: What is the minimum Linux kernel version a Comet Lake-S CPU can run on? I'm wondering if it is possible to run a Comet Lake-S system on a Debian Stretch install with kernel 4.9.0 or 4.19 from backports.
I'm only refering to CPU and chipset (B460) compatibility - I'm aware that there's no iGPU support before 5.x, which wouldn't be necessary anyway.

A: To answer my own question: it doesn't work, the kernel halts.
