--- Comment #8 from Chris Wilson <chris at chris-wilson.co.uk> ---
The root cause is that the ShmPixmap doesn't appear to be valid. The final
failure is that we recuse inside our execbuffer trying to fix things up. That
at least should be fixed by

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.

and so now when you resize, it should just blink and complain bitterly instead.
