Server aborting Please either attach gdb and grab a 'bt full' or run 'addr2line -e /usr/lib/xorg/modules/drivers/intel_drv.so 0x71f90 0x62972' It survives locally. You might also want to check with xf86-video-intel.git, but getting a resolved stacktrace is most important. I tried running X with the '-core' flag, then loading the core dump into gdb to get a backtrace, but there were no debug symbols. So I guess I'll need to compile Xserver and the xf86-video-intel driver with debug symbols and then try again. Created attachment 67528 [details]
Backtrace
xorg-server 1.12.4 and xf86-video-intel 2.20.8 compiled with -ggdb. Not stripped.
/usr/bin/X run with -core flag, crash reproduced.
`gdb /usr/bin/X /core`, 'bt full'

Created attachment 67221 [details] Xorg crash log Xorg often crashes when enabling the Web Inspector in Chromium. The crash only seems to occur with SNA enabled. Tested kernel versions 3.5.3 and 3.6-rc3; crash happens in both. To reproduce: 1. Open the Chromium browser. 2. Repeatedly press Ctrl+Shift+i to open and close the Web Inspector. 3. Xorg will crash with ~20% probability each time the Web Inspector is opened. Distro: Arch Linux Ivy Bridge i5-3570K HD4000 graphics. xf86-video-intel 2.20.7 xserver 1.12.4 Display connected with DisplayPort.
