4.15.0-12 had the same problem, please see #1756455 [1] (which is
absolutely the same as this one).
I have also tried all mainline kernels from 4.15.3 up to 4.17rc1, and
here are the results:
* all mainline kernels in branch 4.15 do NOT have any issues
* starting with mainline 4.16.0 it is

The system was originally installed using a snapshot ISO which had
kernel 4.15.0-10. And everything was working great, system was powering

daily. So everything was working fine with 4.15.0-10.11.

"Generally" means that 4.16 behaviour seems to be even more random -

OK, as expected linux-firmware upgrade seems to be unrelated. After
doing more than two dozen shutdowns with each kernel (4.15.0-10 and
4.15.0-12) I see the following pattern:
* secure boot enabled or disabled makes no difference
* kernel 4.15.0-10 correctly powers off system (halt -p) every
