If the commit you bisected is actually the culprit, this is an issue with the
memory controller and the displays on the GPU. When we reprogram the memory
controller we need to stop all the GPU memory clients. We used to disable the
display controllers but this caused additional flicker on boot up and caused
hangs on some cards. So we switched to the current method which was
recommended by the hardware team. This avoids the flicker by just stopping the
MC interface in the displays but leaving them enabled and also fixes hangs
related to this on a number of chips. Unfortunately, it seems to cause other
problems in certain causes.
