I have been running with that in my GRUB_CMDLINE_LINUX for a couple days
now. It's unclear whether it is having an impact. Crash rate does not
seem to be reduced, and I am often unable to see the logs after it
hangs.

I was trying to test out the upstream kernel this weekend. One of the
steps is to disable 3rd party libraries (like nvidia). Is there any way
to identify all the libraries that have to be disabled? Or better yet -
any way to install the kernel into a live usb image?

Unfortunately, the system is unusable this morning. Still trying to
recover it. May have to flatline it again.
It seems I have gotten myself stuck in a loop:

2. after that happens a few times, the NVME needs fsck'd because of corrupt
