I'm also aware we never get enough testing coverage before stuff hits your tree, we'd need 1000s of testers to run drm-next and we just don't have that variation. So yes when new features hit -rc1 with the drm they nearly always cause regressions, its just not possible to test this stuff on every GPU/monitor/bios combination in existance before we give it to you, that just isn't happening. Like radeon pageflipping caused machines to completely hang and I didn't find out until -rc7 due to lack of testing coverage.
Not that I have much credibility to be talking here, but as a nouveau user with a problem setup where I cannot seem to find anyone to help [1], I wonder if getting support for the absolute latest GPUs into mainline perhaps should not be the highest priority. Also, have you considered the possibility that taking longer for code to hit Linus' tree would have the effect of increasing your tester base for drm-next? If I had a new video card that was giving me a blank screen, I would certainly be ready to try a testing kernel tree if I thought it would get me some level of functionality.
