TWIMC: A power button press works fine for me on Fedora 25 Workstation
Edition (running 4.9 currently, but I think it worked with the stock
Fedora kernel, too) on my 9360. From a quick look in the bug report you
mentioned it looks a bit like you might need to enable INTEL_VBTN in
your kernel config. From the Kconfig:

   This driver provides support for the Intel Virtual Button interface.
   Some laptops require this driver for power button support.

HTH, Ciao, Thorsten
