That's just the driver noticing that something is amiss, and
complaining loudly about it. Two things:
- Can you please boot with drm.debug=0xe, reproduce the bug and then
attach the complete dmesg? That should spill tons more useful
information about how we ended up in this broken state.
- Is this a regression?
Also, can you please file this as a bug against DRI -> DRM (Intel) on
bugs.freedesktop.org, to make sure we don't lose track of it?
Thanks, Daniel
