To add some closure to this ticket:
Lenovo support had to visit me 3 times:
- first they replaced the SSD -> same problem
- then they replaced the SSD adapter and cable -> same problem
- lastly they just replaced the whole motherboard -> fixed the problem for
Windows
So it seems I definitely had a
Had the same problem in Windows (I think, harder to diagnose on Windows), even
after installing updates for BIOS, firmware & drivers, so this is probably a
hardware problem.
Lenovo support should visit me soon to fix the problem (with new hardware),
I'll give an update after that.

I'm starting to think it isn't a software issue.
I tried to solve it again because it was becoming impossible to work, and
decided to install Ubuntu MATE 16.4.3 LTS (kernel 4.10.0-42-generic) because I
read some people had less problems with NVMe drives on that.
The problem persisted however.

I tried it and it worked for 1 day, but it just happened again.
Maybe this isn't a problem with Ubuntu/Linux after all?
I have already checked the physical connection of the drive and as far as I
could find out the drive itself is healthy too, so I have no idea what the
problem might be...
Any mo
No, it just had the best result out of everything I have tried. It still hangs
occasionally, especially after a cold boot.
The kernel from #13 is comparable so far: ~2 hangups per day, mostly after cold
boot.

No problem, I am very grateful for your help!
As I said in the "What have I tried"-section (sorry if it got lost in
all the info, I tried to give as much as possible), yes I have tried
that and yes I have the same problem. It seems to be worse actually when
I put 0 as latency.

Well...
Seconds after my previous message it happened again.
So it seems the upstream kernel does not fix the problem.
I'm adding GRUB_CMDLINE_LINUX_DEFAULT="nvme_core.default_ps_max_latency_us=250"
again.

I installed the latest upstream kernel and will report back with the
results.

I assumed it would also make the most sense to remove the
