This bug is driving me nuts!

First time, it frequently happened when I ran Sway and LXDE at the same time, where my entire graphics stack would freeze and I would be unable to switch virtual TTYs or even kill X, even with kill -9 on everything.

Now, I am experiencing this bug again, this time with SteamVR, and at a MUCH higher frequency. It seems to happen, fairly randomly, whenever I start SteamVR, but seems to be more likely when my system has been running for a long time, or when Waterfox has been running for a long time.

A couple weeks ago I found a way to reset my GPU as a workaround to the bug (https://www.reddit.com/r/linuxquestions/comments/lpiwkg/how_to_reset_graphic...), but today, this did not work. My screen went black, but I was still unable to kill -9 X, even after trying the reset many times. In dmesg, there were messages about the reset still being in-progress, but I did not see anything seem to change. Eventually, I decided to give up on gracefully fixing this bug with no downtime to my website and poweroff, then hold the power button of my computer after the HDD activity light went off as even powering off doesn't seem to work properly with this bug. Only then, could I reboot and recover.

I have attached the end of the most recent dmesg where this failed. I also have more dmesgs that may or may not be the same bug, but the attachment field only allows for one.
