Nasty issues with Linux 4.2, Skylake and NVMe

Until Linux Mint 18 will be released I thought it would be OK to go with the current release - 17.3. It's OK most of the time, until it breaks in various ways.

Mainboard: ASUS Z170-DELUXE
CPU: Intel Core i3-6320 3.90 GHz (Skylake)
SSD: Samsung 950 Pro 256GB M.2
Linux kernel: 4.2.x

Trying kernel 4.4 (available from Ubuntu) renders an unbootable system due to some strange issues configuring GRUB I think - I just didn't have the time to investigate in detail, although I tried chrooting and updating grub from a live session, without success.

I might as well consider another distro if kernel 4.5 or newer fixes these issues. Sometimes the system freezes so badly not even the (hardware) reset button doesn't work. Other times the NVMe controller simply throws in the towel [1] and I get left with some partially running programs, everything running from RAM, because the storage disappears until I reset the PC.

It's been two and a half terrible months since I got this new PC and lacking the time to find out answers it's frustrating I have no idea who to blame. So I guess I might as well blame myself for going with "the latest and greatest" from Intel without properly researching compatibility.
