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?
