I found that the real commit that needs to be reverted is 3e26c5feed2add218046ecf91bab3cfa9bf762a6 from https://patchwork.kernel.org/patch/10993697/, meaning that 5.2 kernel is also affected

I am working to identify a minimal changeset to restore functionality on this system

Hi Jeremy,
I've looked at the post at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1836630,
and it seems that it is a nvidia DKMS module issue which has already been fixed.
