<pre>I've no idea what's caused this error state, hence filing against the kernel as
a placeholder.
I have code using VA-API to decode a 4K video and render to an X11 window with
VA-API/X11. I then have an OpenGL compositor downscaling this window to
1920x1200 for scanout. Something in this stack is causing the GPU to hang and
generate an error state.
I'm running Fedora 20 x86_64 with patches on a Haswell Intel(R) Core(TM)
i3-4330 CPU.
Software versions are (I can supply SRPMs and x86_64 binary RPMs for all of
this if needed):
xf86-video-intel: xorg-x11-drv-intel-2.21.15-5.fc20.x86_64
xserver: 1.14.4 patched to support high dotclocks on HDMI.
mesa: mesa-dri-drivers-10.1.3-1.20140509.fc20.x86_64
libdrm: libdrm-2.4.54-1.fc20.x86_64
kernel: kernel-3.14.4 patched with extras from <a class="bz_bug_link

I'm connected via a DP to VGA adapter at the time:

I'll attach a compressed error state shortly.</pre>
