dmesg log

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

Does that also happen with dpm disabled?

Without "radeon.dpm=1", all played normally

Also on kernel 3.11rc5

dmesg log

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.


Arch Linux testing packages except for the kernel which is custom build.
Card: Radeon Mobility 4650 HD
Linux kernel: 3.11rc6 (commit: b36f4be, it's called -dirty in the dmesg log but I don't know why, will try to figure that out)

OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD RV730
OpenGL core profile version string: 3.1 (Core Profile) Mesa 9.2.0-rc1

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):

But right after that my X session was killed and the X server kept exiting with bus errors when starting new ones (see attached log).

Is this still an issue with this kernel patch?

My laptop is dead, I can not test this anymore.

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.

dmesg Linux 4.0.2 + patch "Disable semapthores..." #2

Another try with the patched kernel.  This time I quit mplayer while stil playing ok a run again.  Maybe contains useful info.

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.
