Description Leho Kraav (:macmaN :lkraav) 2009-10-13 10:19:33 UTC

XBMC is multiplatform OpenGL media center application. it has a python based plugin & scripting system. this crash occurs when these python scripts start setting up their display or drawing some controls.

i'm running gentoo 2.6.31-tuxonice, xorg-server-1.6.5, mesa 7.6, xf86-video-intel-2.9.0. X crashes with this error:

X Error of failed request: BadAccess (attempt to access private resource denied)
Major opcode of failed request: 152 (GLX)
Minor opcode of failed request: 26 (X_GLXMakeContextCurrent)
Serial number of failed request: 2467
Current serial number in output stream: 2467

XBMC stack trace is as follows:

these scripts work when run on other platforms and other video cards (nvidia, ati).

any recommendations how to get to the bottom of this much appreciated.

Comment 1 Leho Kraav (:macmaN :lkraav) 2009-10-13 13:05:57 UTC

previous desc referred to running XBMC SVN 22528.

upgrading to SVN 23692 has improved this issue, will test and report further.

Comment 2 Eric Anholt 2009-10-23 15:06:20 UTC

handing glx issue to idr.  also, please explain what you mean by "improved"

Comment 3 Chris Pimlott 2009-11-02 16:56:12 UTC

I'm also seeing this issue with Boxee, an XBMC fork.  It happens 100% of the time after the initial Boxee login screen:

X Error of failed request:  BadAccess (attempt to access private resource denied)
  Major opcode of failed request:  153 (GLX)
  Minor opcode of failed request:  26 (X_GLXMakeContextCurrent)
  Serial number of failed request:  2896
  Current serial number in output stream:  2896

The issue started after upgrading from Mythbuntu 9.04 to 9.10, going from intel driver 2.6.99.1+git20090402 to 2.9.0+git20091026.

Comment 4 Leho Kraav (:macmaN :lkraav) 2009-11-02 23:35:23 UTC

i was actually thinking about closing this particular bug, because the newer XBMC SVN builds don't exhibit the same crash anymore, but obviously it would be nice to know what kind of NEEDINFO we could provide to debug this kind of thing?

Comment 5 Nick Andrade 2009-11-03 11:35:28 UTC

I can confirm seeing this issue in both XBMC and Boxee with at least Intel drivers 2.8.0 and Xorg server 1.6.2, possibly prior; the older (pre-UXA) drivers worked fine on the same hardware (Intel GMA 4500).

I think the NEEDINFO was in reference to the statement in comment #1 "upgrading to SVN 23692 has improved this issue".  What is meant by improved?  It sounds like XBMC made some changes, and the bug is no longer reproducible.  Is that correct?

I tried version 9.04.1+svn20091002-0.0 on Debian with tip of Mesa, X server, and xf86-video-intel, and I was not able to reproduce this bug.

Comment 7 Leho Kraav (:macmaN :lkraav) 2009-11-10 02:17:26 UTC

Yes, it would appear that some changes in XBMC stopped this particular bug.

Comment 8 Leho Kraav (:macmaN :lkraav) 2009-11-23 01:58:20 UTC

after changing to compiling built-in python in XBMC, i have no more crashes related to this plugin. i believe that was the culprit all along for me. not sure about the other cases here.

Comment 9 Ian Romanick 2009-11-23 10:44:33 UTC

Since this bug can no longer be reproduced, I'm going to close it.
