<pre>Hi Jim,
I have tried latest drm-intel-nightly(from Ubuntu repository) with
patches from the attachments:
- system still hangs during kms_plane test(in the same place with the
same error as without these patches. Refer to log here:

href="show_bug.cgi?id=94822#c5">https://bugs.freedesktop.org/show_bug.cgi?id=94822#c5</a> )
- but I haven't tried yes to reproduce the "main" problem with these
patches(kernel hangs during boot when several displays are connected).
I'm going to provide the results of this test on Tuesday.
It seems that there is some mess in the discussion. Let me put it in
order:
- "main problem"(kernel freezes during boot) can't be reproduced with
vanilla 4.6.rc5 kernel;
- but kms_plane test still hangs on all available
kernels/drm-intel-nighty with and without patches from

The second problem is not important for me, but I can conduct more tests
or collect more detailed debug output if needed.
Please also note that I'm using SKL-U SoC system, not Y or H variant.
Best regards,
Edgar Cherkasov.</pre>
