--- Comment #5 from Eero Tamminen <eero.t.tamminen at intel.com> ---
Still getting these.  Following is with i965 used for the desktop and Iris used
for the benchmark:

[ 7275.093815] Iteration 1/3: synmark2 OglHdrBloom
[ 7284.938454] i915 0000:00:02.0: GPU HANG: ecode 9:1:0x00000000, hang on rcs0
[ 7284.938458] GPU hangs can indicate a bug anywhere in the entire gfx stack,
including userspace.
[ 7284.938459] Please file a _new_ bug report on bugs.freedesktop.org against
DRI -> DRM/Intel
[ 7284.938460] drm/i915 developers can then reassign to the right component if
it's not a kernel issue.
[ 7284.938461] The GPU crash dump is required to analyze GPU hangs, so please
always attach it.
