Hi!
And if you can indeed reliably reproduce this a bisect could be really useful.
And we have a winner here :-)
Ok, it was not as painfull as I feared.
It does not revert cleanly, but doing it by hand was not that bad.
Best regards, Pavel

Rings should be idle before issuing sync_flush (in intel_ring_setup_status_page). This patch moves the ring disabling before doing the HW status page setup.
