            Bug ID: 67994
          Assignee: dri-devel@lists.freedesktop.org
           Summary: System freezes when playing video on open source AMD
                    drivers with VDPAU
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: scorp.exe@yandex.ua
          Hardware: x86 (IA32)
            Status: NEW
           Version: XOrg CVS
         Component: DRM/Radeon
           Product: DRI

Kernel - Linux 3.11rc4
Version mesa-common-dev - 9.2.0~git20130729+9.2.9b8ad643-0ubuntu0sarvatt~raring
Version libg3dvl-mesa - 9.3~git1308091520.e8d897~gd~r
Driver - Gallium 0.4

To repeat the freezing - start the video on player with support for VDPAU
(mplayer or XBMC), stop it, and then run another video.

Please post the full dmesg output, especially the bootup sequence.

Does that also happen with dpm disabled?

Look alike bug here: screen goes black and freeze for a while when playing the
second video using VDPAU with mplayer. Upon "screen return", the whole display
is corrupted and unusable, requiring reboot.

I don't know why, will try to figure that out)

New dmesg log with patched kernel

This is the new dmesg log. I tried the patch but the bug is still here in my
case.
However the "Bad LCD record" error is different now and some lines in the end
are not in the new log.

X server logs

Note: if I quickly kill the second mplayer right after the start of the video I
can avoid the crash, but UVD won't work anymore and mplayer will permanently
end with some errors (if VDPAU is forced):

--- Comment #14 from zimous <zimous@matfyz.cz> ---
Same problem here, resurrecting the bug.  The situation is better with the
"Disable semaphores for UVDv1" patch from bug #85320, but still not completely
working.  Tested with:

mplayer -vo vdpau -vc ffh264vdpau movie.mkv

It is an older machine (but still serving well):

CPU: 32bit Intel P4
MB: MS-6728, Intel 865PE; Notably no MSIs!
GPU: RV730 [Radeon HD 4600 AGP Series]; The "abomination" on AGP!
distro: gentoo
gcc: 4.9.2
xorg: 1.17.1
mesa: 10.5.2 (r600, llvm enabled)
xf886-video-ati: 7.5.0
mplayer: 1.2_pre20150214
ffmpeg: 2.6.2

1) Stable kernel 4.0.2
- Movie plays for a few seconds, then the whole desktop freezes.
- Keyboard dead, display dead. Ctrl+F1 to switch to console not possible.
- Immediate poweroff (ACPI button) makes a clean shutdown.  After few seconds
not possible, only hard reboot.
- Relevant line of dmesg: radeon 0000:01:00.0: failed to get a new IB (-35)

2) Stable kernel 4.0.2 + patch "Disable semaphores ..."
- Movie plays for a longer time (10's of second) well.
- Then the video stucks in a short loop (~second), while audio, subtitles and
rest of the destop still ok.
- After longer time (~minutes) audio and the whole desktop freezes.
- But I can do Ctrl+F1 to switch to console and even restart X, but the image
is corrupted.
- Relevant line of dmesg: radeon 0000:01:00.0: failed to sync rings (-35)

3) Kernel 4.1.0-rc2 + ~airlied/drm-fixes (commit 3790e39)
- At first, almost the same as in 2), maybe the times are even longer.
- But in the end, the whole system freezes, no Ctrl+F1, no clean poweroff.
- I have no dmesg saved (at the moment) due to the fatal crash.

Eh, now I realized that this bug is also about DPM.  In my case "radeon.dpm=0"
does not help.  Sorry for that, I should have filed a new bug.

Also, after more testing it seems that 4.1.0-rc-2 + drm-fixes behaves more like
4.0.2 + patch.  It depends, sometimes Ctrl+F1 / restart X / clean poweroff is
possible, sometimes not.
