Bug not fixed, when enabling dri2 of driver, with kernel-4.2rc5/mesa git head/xf86-drv-video git head/drm git head.
Hardware is "Thinkpad x250" with "00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09)"(00:02.0 0300: 8086:1616 (rev 09)).
There is still no easy way to reproduce it, generally, I started ltp test and clicked kickoff menu or some popups. after serveral minutes, segfault happened.
