Nvidia Halting Solved on Pop Os
I'm on Pop!_OS 22.04 LTS in my Dell XPS (and curse the day I ever bought this box) running an Nvidia GeForce GTX 1660 Ti. I get sporadic freezing.
After a whole lot of --research-- panicked googles, it looks to be a problem with the PCI Power Management in the kernel, and shutting it off seems to fix. To do that, I edited /boot/efi/loader/entries/Pop_OS-current.conf and added to the options line : pie_aspm=off pci=nommconf and restarted.
