After looking at your dmesg, I believe you load the Radeon kernel driver
from loader.conf. Was it the case with r284325M as well? Sometimes, it
appears that loading the driver from loader.conf leads to reduced
performance.

The only change which was made to the DRM subsystem between the two
commits you mentionned is r285002. Can you try to build this commit,
then its parent, to see if it is the culprit and isolate the problem?

Thank you!
