IIIRC when I was working on improving the gamma stuff recently (none of which has been posted yet) I was seeing some underruns when turning the fancy CHV color managagement blocks on/off. But I can't immediately recall if I figured out a way to avoid the underruns or not.

This issue occurs only with drmtip build. Changing the priority to Medium.
