The plot thickens, now 6.7.12 as compared to 6.7.11 which failed hibernation with busy work queues¹ and 6.7.9 + bcachefs downgrade fixes fails hibernation with the same error message than 6.8.1:

Not doing it today or probably the weekend, but now I have some actionable git bisect plan without bisecting between major kernel releases which as I have been told between 6.7 an 6.8-rc1 can lead to non working modeset graphics on AMD Ryzen in between.
It seems now I only need to git bisect between 6.7.11 and 6.7.12 to find the patch that breaks hibernation on 6.8.1 as well. However first I will briefly check whether 6.8.4 hibernates okay.
