There is a patch I posted a while ago for the same problem that waits for
retrace with a timeout - so even if the bit is cleared we timeout after
1/60 of sec (approx) and everything is fine anyway.
Also, Michel, while you are at it - could you modify the irq handler in
DRM to *only* clear bits that it is actually interested it ? Otherwise it
clears capture and gui_dma IRQs which GATOS km driver needs and which are
not used by drm at all.
