Since my last system update (including an update of xorg-server and libdrm) I
have random X-Server crashes and freezes. With xf86-video-intel-2.99.917-r2,
which worked fine before the update, I got "Fatal server error:
has_coherent_ptr:1532 assertion '!priv->cpu_bo->needs_flush' failed" (see <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - Fatal server error: has_coherent_ptr:1532 assertion '!priv->cpu_bo->needs_flush' failed"
href="show_bug.cgi?id=90053">bug
#90053</a>), so I switched to xf86-video-intel-9999 (Git).
Now I get errors like this:

I created two backtraces using gdb, I don't know if they are helpful. The
second one indicates that the Intel driver is involved. If this a xorg-server
issue please reassign.
I have a dual head setup (using ZaphodHeads) - don't know if it is important.
My configuration:
System: Intel Celeron G1840
OS: Gentoo Linux
Kernel: 4.4.0
xorg-server: 1.17.4
libdrm: 2.4.65</pre>
