Hi

What are the exact steps to reproduce, and how often do you get the bug when
you do these steps? All that is needed is to wait until the machine enters DPMS
state?

Can you please boot passing drm.debug=0xe as a Kernel argument (you can do that
in grub), reproduce the bug, then attach the output of dmesg here?

I find it weird that you have a VGA port on an ULT machine. Can you please post
the output of the "xrandr" command?

Just a notice: we are aware that some converters (e.g., DP->HDMI, HDMI->DVI,
etc.) sometimes may cause problems. Not all converters cause this behavior, so
if you could try to test other converters (or a DP monitor), it would be nice
to know .

Thanks,
Paulo
