dmesg output from booting drm-tip with drm.debug=0x1e and psr enabled
Current drm-tip contains commit 598c6cfe06900505ae16a355599e9f08432f4d7a
(drm/i915/psr: Enable PSR1 on gen-9+ HW). On a MacBookPro13,3 (Skylake, gen9
gpu) this results in the screen flashing at about 3Hz when the display has no
changes. Removing that commit or booting with i915.enable_psr=0 fixes this
again.</pre>
