Ah, okay.

Thanks for testing; may I ask for two more test rounds, first current
drm-intel-nightly branch of <a href="http://cgit.freedesktop.org/drm-intel">http://cgit.freedesktop.org/drm-intel</a>, and then
drm-intel-nightly + the patch from <a href="show_bug.cgi?id=92975#c4">comment #4</a>.

<span class="quote">> BTW, no the patch, no "*ERROR* MOCS failed" in dmesg.
> if with the patch, there is "*ERROR* MOCS failed</span >

This is expected, thanks for checking.</pre>
