<pre>I had Mesa snapshot from 2016/11/09 running fine but with one from 2016/11/25 I
have Xorg lock-up.
5248 tty7 Dsl+ 0:06 /usr/lib/xorg/Xorg -nolisten tcp -auth
/var/run/slim.auth vt07
All other processes run fine, I can connect pc using ssh, but Xorg does not
react to keyboard (C+A+F1, C+A+Bs), so the only way to restore system is
REISUB, even after reboot command the system doesn't reboot, the screen is
blanked so I don't see what's going with it.
I tested this issue only with Black Mesa game from steam.
I can provide the last 20 lines of strace -p <Xorg's pid>, but they look
useless.
After git bisect and patch -R I've found a commit causing this issue:
