            Bug ID: 98907
           Summary: commit bf75ef3 causes Xorg lock-up
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: 375gnu@gmail.com
        QA Contact: dri-devel@lists.freedesktop.org

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:
