--- Comment #6 from Mario Kleiner <mario.kleiner at tuebingen.mpg.de> ---
Also looking at the current ati-ddx, there have been changes to the logic since
i last touched that code a long time ago. Functions like
radeon_dri2_extrapolate_msc_delay() and radeon_get_interpolated_vblanks() which
seem to tinker with the values which go into the check that triggered these
warnings in the log. Some kind of adjustments for dpms off periods? Maybe some
off-by-one error there due to some rounding?
