Yeah, filing a bug on fdo to keep track of this should help. Please
add a [gm45 regression] tag to the summary so that it shows up in our
queries at the right spot ;-)

One thing to test would be to give -nightly (or drm-intel-testing as
of today) a shot. We've merged a few patches recently to slightly
improve the ring init sequence in the generic code, they might
actually help here. Sorry for not correlating them with your patch
when I've merged them, only just realized this now.

Thanks, Daniel
