Is yours a SFF model 780? Overheating can cause freezing, and small case 
Dells, like other compact case PCs, are particularly susceptible to 
overheating if allowed to accumulated dust and/or tobacco tar, particularly 
on CPU cooler and/or within PS. Dust collected on tar acts as an insulator, 
containing heat within the source components. If you're sure overheating is 
not your problem, run memtest86 overnight or longer. You might have failing 
RAM. It happens. Sometimes simply reseating RAM will help if testing produces 
errors, but don't count on it.


I can't recall my SFF 780 ever doing as yours with any Linux kernel all the 
way back to 3.11.7 and up through 4.5.4, and servers 1.14.x through 1.18.3.

This is absolutely correct, sadly the existing Makefile.sources
(ab)use makes things hard to grasp.
The 'hard to grasp' part being - this (and other) Makefile.am files
are missing the definition of the *PROGRAMS, *LTLIBRARIES, etc.
variables thus the whole file (and this hunk and particular makes
things harder to read.

Ideally one will give clearer (non-autoconf specific) names of the
variables in the Makefile.sources and move the PROGRAMS... bits into
Makefile.am. That is rather evasive so I'm not sure if you're up for it.
Example (note it has some ~unrelated comments/nitpicks)

About the LIBDRM_INTEL_BENCHMARKS -> changes (and the corresponding 
changes to tools/lib/etc.) this would change the Android.mk behavior too.
The Android.mk changes would make it deviate from the the standard

[Intel-gfx] Updated drm-intel-testing

[Daniel Vetter]

Hi all,

New -testing cycle with cool stuff:
- some polish for the guc code (Dave Gordon)
- big refactoring of gen9 display clock handling code (Ville)
- refactoring work in the context code (Chris Wilson)
- give encoder/crtc/planes useful names for debug output (Ville)
- improvements to skl/kbl wm computation code (Mahesh Kumar)
- bunch of smaller improvements all over as usual

Happy testing!

Cheers, Daniel

[Intel-gfx] Still trying to isolate video freezes

[Chris]

In an effort to try and figure out why the video on my Dell Optiplex 780
keeps freezing I've been advised to run the latest kernel to see if it
may fix the problem. Today I installed 4.6.0-997.20160502_amd64.deb
and when booting it would not finish at all. There were some statements
about not loading root and also about not finding a drive. Is there a
way that I can save all this information so that I can add it to a bug
report I've filed a long time ago. I'm now back to the kernel below in
my sig. Since I'm not smart on any of this I'm also wondering what the
attached means, if anything at all.

Chris

[Intel-gfx] iommu/vt-d: Use per-cpu IOVA caching, suspend-to-ram causes machine hang

[Marius Vlad]

Hi Omer the following commit introduced a regression when doing
suspend-to-ram. The machine never wakes up. We have more than
a few machines that hang: SNB-i7-2620m, IVB-3370, HSW-4470r, BDW-5600u,
BDW-525u.

You can easily replicate by doing a rtcwake -s 10 -m mem.

iommu/vt-d: Use per-cpu IOVA caching
