[Cross-post from LKML; apologies if you've all already seen this] Hi, Between 3.13.5 and 3.15.4, suspend became partially broken on Macbook Pro 15 (late 2013): a few minutes after wakeup from the *second* suspend following a fresh boot, the screen will randomly turn itself off at shorter and shorter time intervals, and turn itself back on after a few seconds and/or user interaction. Eventually, after 4 or 5 such cycles, the screen refuses to turn back on altogether, and the system must be rebooted (closing the lid again has no effect). When the screen turns back on, there is usually some transient corruption (full screen is displayed shifted to the right by 1/10th of its full width, cutting off the right side, which wraps back to the left). This corruption disappears after additional user interaction that forces a re-render. The issue is still present in Linus' tree (v3.17-rc1-22-g480cadc2b7e0). Before I get started trying to bisect this slow-to-reproduce problem, has anyone any idea of possible causes?
