Hi Eric, Thank you very much for the patch. With the new kernel I don't see the bouncing on HDMI problem. I am using HDMI to DVI cable to test 1080 as I don't have 1080 HDMI monitor. With the new kernel Linux does not drive the DVI monitor at all. I switched to 720 HDMI monitor and now there is output signal but I get horizontal scrolling lines across the screen! I don't see this problem with u-boot or Freescale kernel. Have you seen this problem before?
