There are nearly 600 commits between the working and non-working kernel. Rather than work on ~8-9 bisects steps, I've built 5 test kernels that just the relevant i915 driver commits reverted between the working and broken kernel.
Please work through the kernels in revert1 through to revert5 one by one (install, reboot, test for a while) and let me know which ones work fine and which ones cause the fan to kick in because of overheating.

I've put the .debs at the following location:
https:/ /kernel. ubuntu. com/~cking/ lp-1853044/
Please can you test the kernels in https:/ /kernel. ubuntu. com/~cking/ lp-1853044/ revert1/ first. Install the kernel, reboot into it, and check it is the correct one using:
uname -r

Thank you!
