The final failure is that we recuse inside our execbuffer trying to fix things up. That at least should be fixed by commit 9a5ca59d2b7b209e6f56dd3f94d4ae6f06e1ecdc Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>> Date: Wed Oct 15 16:51:42 2014 +0100 sna: Prevent recursion during last-gasp disabling of outputs If we fail an execbuffer, we disable outputs and try again. (In case we have severe fragmentation issues and need to rearrange the scanouts in GTT.) Afterwards we re-enable the outputs, but this causes us to flush the pending rendering and so recurse into the execbuffer. Prevent this with a slight hack during enabling of outputs.
