When I tried run video (vlc player or youtube in chromium browser) on external connected monitor(VGA) I got system freeze. I see this in dmesg: [ 6456.881715] [drm:ring_stuck] *ERROR* Kicking stuck wait on render ring [ 6456.881721] [drm] GPU crash dump saved to /sys/class/drm/card0/error [ 6456.881722] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.

If this is easily reproducible for you, please try testing with i915.enable_rc6=0.

(In reply to comment #1) > If this is easily reproducible for you, please try testing with > i915.enable_rc6=0. I have tried with i915.enable_rc6=0. Same behavior. # cat /proc/cmdline BOOT_IMAGE=/vmlinuz-3.13-1-amd64 root=UUID=71163ea2-5b45-49be-8483-930a3a244b16 ro intel_iommu=on i915.enable_rc6=0 New content of /sys/class/drm/card0/error attached too.
Sorry for the delayed update. Does this occur with a more recent kernel? Can you try with the drm-intel-nightly branch from git://anongit.freedesktop.org/drm-intel?
Hoping this is resolved now, please re-open if not after testing with current software.
