Freedeskop tracker suggests changing value of enable_psr to zero

Confirming current default version is "1"

$ cat /sys/module/i915/parameters/enable_psr 
1

My Dell XPS 13 (9343) running F24 the system hangs after being idle for some time. The issue appeared in 4.7 (when i915 PSR was enabled by default) and remains unresolved in 4.8.1. Setting i915.enable_psr=0 fixes the problem. In my opinion this should be considered as blocker.
