--- Comment #27 from Maarten Lankhorst <bugs at mblankhorst.nl> ---
The patch series I suggested make those issues more unlikely.

Anything between pipe_update_start and pipe_update_end needs to run in a single
vblank. By taking the spinlock in pipe_update_start we get rid of any race
condition, and we can actually finish inside a single vblank deterministically.
