Created attachment 89641 [details] Dmesg log with the described errors Hi, i have a trouble watching some H264 videos when using VDPAU acceleration. What happens is the screen gets completly corrupted (gray bars cover the whole screen) when player plays a certain frame in the video. It always happens at the same point of the video, for some videos it doesn't happen at all. I managed to blindly save smesg output to a file when this happened, and it's filled with these kinds of messages: [ 47.595028] [drm:radeon_cs_ib_chunk] *ERROR* Invalid command stream ! [ 48.303022] Forbidden register 0x0020 in cs at 9 [ 48.303029] [drm:radeon_cs_ib_chunk] *ERROR* Invalid command stream !

[ 57.523022] Forbidden register 0x0024 in cs at 9 [ 57.523030] [drm:radeon_cs_ib_chunk] *ERROR* Invalid command stream ! I'm using Arch Linux with 3.12.1-ck at the moment, but it also happened on 3.11-ck and 3.11 vanilla. lspci reports this card name, it's a Radeon 4570: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV710/M92 [Mobility Radeon HD 4530/4570/545v] I'm using the newest stable mesa 9.2.3 and xf86-video-ati 7.2.0. The issue happens with mpv and mplayer.

Please provide a sample video where this is happening.
(In reply to comment #4) > Please provide a sample video where this is happening. This one seems to cause the same error as my files (can't upload mine due to copyright restrains): http://www.cccp-project.net/beta/test_files/KAA_fumoffu_old_x264_breaks_lavc.mkv I noticed that the playback sometimes finishes sucessfully if i stop moving the mouse completly, but as soon as i start moving it, the breakage is certain.
I can't reproduce the problem. Can you try this with mesa master branch? Thanks in advance.
(In reply to comment #6) > I can't reproduce the problem. Can you try this with mesa master branch? > > Thanks in advance. I just compiled Mesa master using https://aur.archlinux.org/packages/me/mesa-r300-r600-radeonsi-git/PKGBUILD , just added --disable-dri3 flag. The same thing happens, but it seems that i was mistaken about it happening always on the same frame of the video. The mkv file i posted sometimes plays fully without a problem, and sometimes it causes corruption with a seemingly random frame. Same thing happens with my own videos. Could it be that it's a kernel driver bug, not related to Mesa?
(In reply to comment #7) > Could it be that it's a kernel driver bug, not related to Mesa? Not really. The kernel is complaining that mesa is sending down invalid commands, but I have no idea how that can happen. Either we have a very subtile and rare bug somewhere in the userspace driver stack or something is corrupting our command buffer while it gets send to the kernel. What application do you use? Could you try playing with a different one?
> What application do you use? Could you try playing with a different one? It happens with mplayer and mpv while using vdpau. I tried to reproduce this in vlc and it doesn't happen, although i'm not sure it's using vdpau, the ui is a bit confusing.
