I’m having the same problem!
Phone is rebooting instead of powering off.
Just got a new Fairphone 2 (new camera modules) and auto-updated to the newest Fairphone OS (FP2-gms-17.10.1), which should get the modem also to a recent version I guess. “Power off” worked fine!

Then I installed twrp-3.1.1-1-fp2.img and lineage-14.1-20171004-UNOFFICIAL-FP2.zip from here:
- LineageOS 14.1 with OTA updates for FP2
- https://fp2.joutubes.nl/builds/full/
Now “Power off” isn’t working anymore. Instead the phone is rebooting.
I’m not using full-disk-encryption. (I’m planning to do that later on)
WORKAROUND:
Reboot into recovery (tested with TWRP 3.1.1-1) and choose “Power off” in recovery.
