Created attachment 59319 [details] Xorg.0.log after setting the kernel boot parameter it doesn't matter if I try to play h264, xvid or flash-content, video hangs every few seconds. Booting with "drm_kms_helper.poll=0" fixes the issue here. System specs: AMD E-350 CPU in a Zotac Zbox Nano AD10 Plus with "VGA compatible controller [0300]: ATI Technologies Inc Wrestler [Radeon HD 6310] [1002:9802]" Software specs: Debian GNU/Linux "wheezy" (testing), Linux kernel 3.2.12 (Debian kernel image), Xserver 1.11.4, libdrm-radeon 2.4.30, mesa-utils 8.0.1, libgl1-mesa-dri 7.11.2. regards Michael
