NVIDIA GPU periodically falls off bus

Hello all, me and my misbehaving NVIDIA hybrid laptop have returned after a year or so of it being cooperative.

Starting about a month ago, the dGPU falls off the bus (Xid 79) every once in a while. Usually this comes in the form of my going away for a bit and coming back to a black screen (normal) that won't resume on keypresses (not normal). But one time it happened during the process of shutting down so it isn't just when the system is idle.

If I terminate Xorg (and everything else) with SysRq+E then the display returns at the TTY. Changing TTYs while the screen is black doesn't help it come back though.

As far as I can tell from incomplete journals the first time this happened was May 3. The kernel upgraded to 7.0 on April 29 along with nvidia-open-dkms upgrading to 595.71.

Of note is that I've also had a couple weird freezes in Windows 11, starting around the same time, where the display freezes a couple seconds after I enter my password to log in. That makes me hope my GPU isn't just starting to die. Oh, and yes, I checked again, fast startup is disabled.

This issue looks similar and the time frame is similar as well but it could be something entirely different: https://bbs.archlinux.org/viewtopic.php?id=313284

Knowing this, I've currently alleviated the issue by forcing it into P0 via

sudo nvidia-smi -lgc 500,2100
sudo nvidia-smi -lmc 6001,6001

Have you tried similar?
