Just a note that i915drmkms won't apply workarounds to any generation
below gen 8, it will probe and attach early versions but it is a bit hit

The drm driver appears to be missing some gen 7 devices - like the one
in my laptop so you may get a probe failure with that.
Ooh. Haven't come across that before. I also get exactly the same ring
heartbeat issue on my system and looking at the latest linux DRM code
the gen7/gen6 workround code is pretty tiny and trivial to backport.
I've just popped it into my local tree and I'm giving it a try :)
Here's hoping.
