Hi, with 4.6.0-rc4 and -rc6 kernel I experience occasional (every 1-2 Minutes) on my laptop (thinkpad t440s) screen. This flickering has not been there in 4.5. Unfortunately the laptop does not boot with 4.6-rc1.
The laptop screen is connected via eDP. I have two other monitors connected to the dock, conected via DP. They do not show the flickering. There is nothing in the log when the flickering occurs (drm.debug=14). Compared to 4.5.0 I see the following message with 4.6.0 after bootup: [ 5921.720651] [drm] Reducing the compressed framebuffer size. This may lead to less power savings than a non-reduced-size. Try to increase stolen memory size if available in BIOS. I tried to increase graphics memory in bios, however, this did not seem to have any effect. Any idea how to track this down? I'm happy to provide more info.
