--- Comment #10 from Kenneth Graunke <kenneth at whitecape.org> ---
Reassigning to the kernel component since comments #8-9 indicate that it works
with kernel 3.15, but doesn't work with kernel 3.14.9.  It's probably not a
Mesa issue then.

(Also, note the conflicting information in comment #1, which says "HD 4400" -
Haswell GT2 - but then mentions Baytrail.  Based on the NUC product number and
backtrace, I believe this really is Baytrail, not Haswell.)

Manuel, I suspect the kernel guys will suggest bisecting to find the fix.  It's
usually pretty effective.  To find a fix, you want to treat "working" as "bad"
and "hanging" as "good".  Then bisect will find the first "bad" commit, i.e.
the commit that makes it start working.

$ git bisect start -- drivers/gpu/drm/i915 # or just (git bisect start, but
this will probably be faster and ought to work.)
$ git bisect good v3.14.9
$ git bisect bad v3.15
<build and test a kernel.  if working, 'git bisect bad'.  if hang, 'git bisect
good'>
