Repro same stack traces on 510 after some trial and error at: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-510/+bug/1953674

Key discovery there: it reproduces almost every time when my laptop is on battery power with the power cord unplugged, otherwise it generally only happens if I suspend for a certain amount of time.

Also simply having the opencl/CUDA packages enabled also causes suspend problems even if you switch back to NOUVEAU.

I also see some ACPI error messages which only appear to show up with NVIDIA enabled:
