--- Comment #6 from Chris Wilson <chris at chris-wilson.co.uk> ---
Can you add a printk() there to dump the pipe bpp? From your Xorg log we should
only be requesting a depth 24 framebuffer, so I am guessing that it is the new
check for mode->clock > 225000 that is failing.

If you make the debug message:

DRM_DEBUG_KMS("too high HDMI clock (%d > 225000), rejecting mode\n",
adjusted_mode->clock);

and then attach the fresh drm.debug=6 dmesg.
