[i965] X with intel driver crashes on video playback

[David Gibson]

Attempting to play a DVD with either totem-gstreamer or totem-xine nearly always results in a crash. Sometimes the crash is immediate, sometimes the DVD plays for a while before the crash happens. There are two types of symptom:

     * (common) server restart. The bottom part of the screen starts showing junk, then shortly afterwards the X server dies and restarts. According to the Xorg.0.log, the server had a SEGV.
     * (occasional) full system crash. Occassionally instead of just an X restart, the whole system freezes - junk may or may not show on screen as above, but the mouse cursor stops responding as does everything else.

I'm using Jaunty, btw. I was using Jaunty through most of the dev cycle and mostly video playback was working fine. This bug seems to have come in either shortly before, or after the final 9.04 release.

[David Gibson (dwg)]

Uh.. this may be due to the custom kernel I'm running. I'll need to do some further investigation.

I am using 9.04 and facing the same problem. Xorg.log.0 attached, looks like the same problem.
The crash is coming with every video file i have tried to watch with mplayer, xine, vlc player.
sometimes the video crashes right when the video starts, sometimes the trigger seems to be a overlaying window or anything else opening like the right mouse button menu or the sound louder buttons. Result is always a X server restart, never have faced a total system crash up to now.

Could you (either of you, but David with a standard kernel) try and do a full backtrace as described on https://wiki.ubuntu.com/X/Backtracing ? It looks a bit involved, but note the first paragraph about apport-backtracing. This should be fairly automatic. It will file a new bug by default, but that should be okay. Just link to it from here.

One more thing: We would need the output of `lspci -vvnn` from both of you to identify your exact hardware. And David, we'll focus on the first problem for now. The second is probably a different bug (possibly a GPU freeze, look at https://launchpad.net/xserver-xorg-video-intel/+bugs?field.tag=freeze and see if you find that bug there).

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

Sorry, looks like this was a bug with my custom built kernel. The problem hasn't reoccurred since I switched back to the standard kernel.
