Created attachment 73379 [details] xorg.conf When running a program using the DRI on a screen with an interlaced video mode, the screen freezes periodically, i.e. every screen update stops, even the movement of the cursor. This occurs approximately every 10 seconds and lasts for about half a second. Everything else, e.g. audio output, appears to run normally. The symptoms apparently are the same as those of bug 45674, but I'm seeing this issue only when using an interlaced video mode. System environment: -- chipset: 945GSE -- system architecture: 32-bit -- xf86-video-intel: 2.19.0 -- xserver: 1.12.4 -- mesa: 8.0.5 -- libdrm: 2.4.40 -- kernel: 3.7.1 -- Linux distribution: Debian Wheezy (kernel from experimental) -- Machine or mobo model: Intel D945GSEJT -- Display connector: VGA Reproducing steps: - Start X with an interlaced video mode (see xorg.conf for the Modeline I'm using) - Make sure that the DRI is in use (e.g. by activating desktop effects in KDE) - Start a program which countinously produces output or watch a video or just move the cursor around

Ah, short pause every 10s is hotplug polling. echo 0 > /sys/modules/drm_kms_helper/parameter/poll Or try drm-next for Daniel's kms locking rework.
