I bisected it and found that it was introduced by commit 5d5b2b8ee203ae2274fc7d13ed38d2945facca9e. The back trace of the crash is as below: Backtrace: 0: /home/gongzg/gfx-dev-test/src/xserver/hw/xfree86/Xorg (xorg_backtrace+0x3b) [0x81b5fdb] 1: /home/gongzg/gfx-dev-test/src/xserver/hw/xfree86/Xorg (mieqEnqueue+0x15c) [0x8195a0c] 2: /home/gongzg/gfx-dev-test/src/xserver/hw/xfree86/Xorg (0x8048000+0x40782) [0x8088782] 3: /home/gongzg/gfx-dev-test/src/xserver/hw/xfree86/Xorg (xf86PostMotionEventM+0xf1) [0x80c5671] 4: /home/gongzg/gfx-dev-test/build/lib/xorg/modules/input/evdev_drv.so (0xb7623000+0x2fdf) [0xb7625fdf] 5: /home/gongzg/gfx-dev-test/build/lib/xorg/modules/input/evdev_drv.so (0xb7623000+0x4229) [0xb7627229] 6: /home/gongzg/gfx-dev-test/src/xserver/hw/xfree86/Xorg (0x8048000+0x67fcf) [0x80affcf] 7: /home/gongzg/gfx-dev-test/src/xserver/hw/xfree86/Xorg (0x8048000+0x8e984) [0x80d6984] 8: (vdso) (__kernel_sigreturn+0x0) [0xb7fff400] 9: /home/gongzg/gfx-dev-test/build/lib/libdrm_intel.so.1 (drm_intel_gem_bo_map_gtt+0x83) [0xb7e9cee3] 10: /home/gongzg/gfx-dev-test/build/lib/xorg/modules/drivers/intel_drv.so (0xb7ea1000+0xd6cb) [0xb7eae6cb] -- intel_uxa_pixmap_put_image 11: /home/gongzg/gfx-dev-test/build/lib/xorg/modules/drivers/intel_drv.so (0xb7ea1000+0xf42c) [0xb7eb042c] -- intel_uxa_put_image 12: /home/gongzg/gfx-dev-test/build/lib/xorg/modules/drivers/intel_drv.so (0xb7ea1000+0x37f8e) [0xb7ed8f8e] -- uxa_trapezoids It's a one line patch. And there is not too much thing to do with UXA code, I guess It may be a libdrm related problem. It's can be simply reproduced in my machine, Use Mozilla 3.6.10 to open the following URL: http://pnp.sh.intel.com/WRTBench/Workload_3.3_rev0.13/iterations_rev11_new.h tml It will iterate many pages and finally give a report. The crash may occur after a few seconds of running. Uncomment that one line patch can avoid this crash.
