The second breaks DC support on my AMD 7750. Kernel panics and I get a black screen on boot. With these two reverted, 6.12 is usable again. Tried to git cherry-pick the fixes but that proved to be difficult to do cleanly. I see 6.6 also has these two commits. Not sure what the proper procedure is to request reverts on stable kernels.
