Hi Mikael,
Which GPU is it: m3 Intel HD graphics 515 / i5 Intel HD graphics 520 / i7 Intel Iris graphics?
Which steps are causing the GPU hang?

It's hard to say what exactly is causing it. Once it was caused by a
"tail -f /var/log/syslog" scrolling text in Gnome Terminal. Another time
it was caused by a web page being displayed in Firefox. A third time it
was caused by switching workspace in Gnome Shell.

I seem to be affected by this as well (same GPU, on an XPS 13" (2016)).
Tried any kernel from 4.3 to 4.5 on Ubuntu, including the drm-intel-next
kernel (4.5.0-997-generic).
A workaround is to add i915.enable_rc6=0 to the kernel boot parameters.

I have now tried this with the latest drm-intel kernel and the newest
skl-dcm firmware (1.26). My libdrm is 2.4.67.
The problem still persists.
A deterministic way to provoke the hang is to run glmark2
(github.com/glmark2).
I can confirm that if I give i915.enable_rc6=0 as a kernel option, the
problem disappears.

Replacing i915.enable_rc6=0 with intel_pstate=disable reintroduces the
GPU crashes.

gpu-rc4-crash.log.gz
I tested this both with Linus rc4 and drm-intel-nightly from today (rc7).
In both cases I still experience a GPU hang with the single (apart from
noresume) kernel cmd line option intel_iommu=igfx_off.
For rc4, I saw a new error code, though:
Mar 10 14:27:46 hat kernel: [ 56.843611] [drm] GPU HANG: ecode
9:0:0x87f99ff9, in gnome-shell [1742], reason: Ring hung, action: reset
I attach the corresponding crash dump file.
This means that the only way, so far, to avoid hangs is i915.enable_rc6=0.
I have confirmed that this is also true for rc7 (drm-intel-nightly).

I have the XPS 13 with the Iris 540. I managed to get Arch working about a week ago. At the time, the core repo included 4.4.1 and had some problems. About the next day I think 4.4.3 hit and I managed to get a working system with that following the Arch wiki (mkinitcpio "... intel_agp i915 ...").
However, after upgrading to 4.4.5 I encounter problems. I don't know if they're hangs per say. Mostly I get blackscreens on boot. But either way, visually the only nicely working system I've got on Iris 540 is:

I can confirm on Dell XPS 13. i915.enable_rc6=0 works. I've tried
i915.enable_rc6=1 to see it was a deep sleep problem, but it shows up
with i915.enable_rc6=1 as well. I tried turning semaphores 0 and 1 and
neither of those helped either. Another bug report mentioned commenting
out a couple of lines in the kernel helped him, but it didn't help me on
4.5.0.
I'm running Debian Stretch with KDE and can reproduce very quickly by
logging in, opening chrome, visit youtube and play a video and set it to
full screen.
Good luck

Let me know what you need to help. Its super easy to trigger by just
playing a video or even just using chrome for more than 5 min.
Can confirm i915.enable_rc6=0 fixes, there still get hiccups fi
watching a video etc, but no full crashes. Kinda hate doing that to my
battery life though.
