From 27d438c56009e5ae632de36fe70985d1aab5e344 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Fri, 8 Aug 2014 11:48:26 -1000 Subject: [PATCH] Revert "drm/i915: Enable PSR by default." This reverts commit b6d547791fd3ef4ccc89ad2556ab01045640aef7. The panel self refresh clearly isn't stable yet, and causes my laptop (Haswell ULT in a Sony Vaio Pro) to have the screen lock up. Maybe it doesn't ever get out of self-refresh, or maybe there are gremlins in the machine that get unhappy. Regardless, it's broken, and it gets reverted.
