My apologies for not responding to your first report, fell through the
cracks somehow. Can you please boot with drm.debug=0xe, reproduce the
WARN and grab the full dmesg (please make sure everything from boot-up
is in there). That's usually enough to figure out what's going wrong
here.

Thanks, Daniel
