The symptoms don't match the recently fixed HSW GT1 bug,
Author: Chris Wilson <firstname.lastname@example.org>

drm/i915: Disable PSMI sleep messages on all rings around context switches
but it is worthwhile trying drm-intel-nightly just in case. I presume it is a different bug though...
Also I tried the following kernels and get hangs for each of them:
- 3.13 ubuntu
- 3.15 ubuntu
- 3.15.0 ubuntu with i915.enable_rc6=0
- 3.17 OpenELEC RC3 which includes those gpu hang fixes:
I let memtest run once with no errors, and have not updatet to the latest BIOS yet.
The system is:
4GB-Kit G-Skill PC3-12800U CL9
Intel Pentium G3220 Box
WD Purple WD10PURX 1TB
I can upload the logs for 3.15 and 3.17 later.

CC'ing Ben as he was recently looking at HSW GT1 hangs.
Hi Knut. Have you tried the latest drm-intel-nightly? A fix went in from Chris Wilson to address issues like this which were mostly on IVB. It did fix our local HSW GT1 hang though.
If that doesn't work, please try this patch:

The equivalent mesa patch
Created attachment 111244 [details]
The limit_max_PS_threads patches seem to improve the situation. So far I experience far less hangs and I didn't actually see one yet while watching the video. So I assume they are very short.
Before hangs would at least disturb playback and often freeze the picture for several seconds.
A new issue ist that now the error state is empty.
it contains this warning:

Your errorstate still has max threads = 101 in the mesa batch that hung.
Please provide dpkg -l |grep 10.1.3, so that I can see which packages did not yet update after your build.

Didn't the patches change max_threads from 102->70? I'm wondering how it could be at 101.
Could it be that gt1 isn't correctly identified somewhere so the wrong max_threads is used, or max_threads is set somewhere else aswell?

This error state did not have the mesa patch in it. It is leading to confusion.

Knut, can you confirm once again the following:
1. Reboot the machine.
2. Using both the mesa and vaapi packages Peter built, reproduce the hang.
3. Try to read error state from sysfs.

This should include Bens latest patch.
Just to recap on the status:
No patches: 2.5s to BSD hang

intel-vaapi + mesa patch: 3-10m to mesa hang
intel-vappi + mesa patch + kernel patch: 20m to mesa hang
intel-vaapi + mesa + kernel + blt only: being tested
While it could be a false correlation, the patches so far seem to have improved the situation. The SNA fix seems to be in master as well, but Knut wasn't able to test that in the limited time he had, so we went with blt only instead.
Expecting an update from Knut on the blt only DDX. Chris, will blit only never emit 3d state?

AccelMethod "BLT" will never emit any 3D commands.

It dies before the end of a reasonably long mesa batch, with multiple PS kernels (actually alternating between a pair of kernels) each only using 70 threads. That does imply that it is not the PS kernel itself, but it could still be the PS state hitting a corner condition for the first time.

Error state with pipecontrol patch
Including the previous patches and this one:
It took 15minutes until crash.
The vaapi patch above was a write up by Ben. I only made it compile and exported it via git.
The error state is once gain hanging in mesa. Seems to me like a failure in the SBE, and then the rest of the pipe dies.
I am not sure mesa doesn't also need an extra pipe control like vaapi. I'm recommending this to try if possible (again a long shot)
the bug is still here.
[drm] stuck on render ring

Dan, yours is almost certainly a different bug. See https://bugs.freedesktop.org/show_bug.cgi?id=80568 (among many others). As the subject states, this bug is specific to HSW GT1.

Always initialize streamout buffers
As the commit message says, there is garbage in the last error state. As an example:

0x001a422c: 0x44954ffe: DWord 1:

This patch should initialize the SOl state regardless of whether we use xfb. It's probably something we want to put in the kernel null ctx setup, but for now we can just test it in mesa.

Similar problem here running XBMC/KODI on an Intel NUC DN2820FYKH (http://ark.intel.com/de/products/78953/Intel-NUC-Kit-DN2820FYKH). I'm running XBMC 13.2 on Ubuntu 14.04 amd64 on two NUCs.

Everything works fine on the N2820 model, but on the N2830 model I get these GPU HANGs. I also tried the current OpenELEC 5.0.0, same problem there.
