Created attachment 53479 [details] Xorg log from the first crash After upgrading xf86-video-intel, I have experienced two occasions of Xorg segfaulting, both events occured while playing video, but I am not sure if this is actually relevant. I am currently using GIT f0acc6c0f15875fd51f6df6c8f13d589f9149771, but first segfault occured with a slightly older revision. Based on the backtrace from Xorg.log, I'd suspect it might have something to do with the putimage changes. Unfortunately the segfault only seems to trigger after hours of use or at least very rarely, so bisecting would not be easy. -- Window manager: WindowMaker 0.92 (obviously not using composition or such) -- chipset: 00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10) -- system architecture: i686 -- xf86-video-intel: GIT f0acc6c0f15875fd51f6df6c8f13d589f9149771 -- xserver/mesa/etc: latest in Debian Testing: X.Org X Server 1.11.1.901 (1.11.2 RC 1) -- libpixman: 0.24.0 (self-built package from Debian Experimental) -- libdrm version: 2.4.27-1 -- kernel version: 3.0.8 -- Linux distribution: Debian Testing aka Wheezy -- Machine or mobo model: Asus P5KPL-CM -- Display connector: VGA
Created attachment 53480 [details] Xorg log from the second crash As you can see, the logs and backtraces are almost identical (apart from the timestamps.)
Can you please convert the addresses to symbols using addr2line -e /usr/lib/xorg/modules/drivers/intel_drv.so 0x74a11 0x769e0
Of course. $ addr2line -e /usr/lib/xorg/modules/drivers/intel_drv.so 0x74a11 0x769e0 /misc/incoming/packages/xf86-video-intel/src/sna/sna_video.c:484 /misc/incoming/packages/xf86-video-intel/src/sna/sna_video_textured.c:259
I wonder how that even survived light testing! commit 7ad3b377a394c9342c3ab2f003d48b7cb3c0891d Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sun Nov 13 17:53:11 2011 +0000 sna/video: Use the right pointer for unmapping Don't just deference any old random pointer, use the one we actually mapped in the first place!
