I was occupied with work and life for the past two weeks, sorry about the wait, but have now managed to find some time to continue pursuing this issue again.

I know the feeling. > This is definitely going to break something else, so not great. I did expect that. The automated tests failing was a pretty good indicator. You put that code in to take care of something. All I did was just tear it down because it happens to work better for me... blunt but functional for my purposes. Seems to need some finesse or a condition to not cause my problem? Yet still function for the reason you put it in there for. I am more than willing to play guinea pig and test patches on my end to improve it with you. > Can you file an upstream bug at > https://gitlab.freedesktop.org/drm/intel/issues/new > and attach dmesgs from booting both good and bad kernels with > drm.debug=3D0x1e passed to the kernel cmdline?
