Apologies, I must have downloaded the wrong attachment (or mess up locally).
Looks like you're now hitting a different issue.

I'm looking at where the GPU stopped to figure out what's wrong.

Here is how to do it :

If you compile the mesa repository with the intel tools activated (I usually
use meson) :

$ cd mesa
$ meson -Dgles2=true -Ddri-drivers=i915,i965
-platforms=x11,drm,wayland,surfaceless -Dgallium-drivers= --buildtype=release
-vulkan-drivers=intel -Dtools=intel -Dbuild-tests=true build .
$ ninja -C build

Then you can run the aubinator_error_decode tool :

$ ./build/src/intel/tools/aubinator_error_decode /path/to/my/card0/error

Then search "ACTHD:", if I take the last error state you posted in should be
this line : 

  ACTHD: 0x00000000 001389f4

Then search with that address : 001389f4

0x00135b04:  0x78150009:  3DSTATE_CONSTANT_VS 

This is the instruction triggering the GPU hang.

In the previous error state, it was a PIPE_CONTROL (which was related to the
other bug I mentioned).

So looks like the patch helps.
Is your machine hanging as often with this patch?
