NVIDIA definitely has stability issues, newest drivers still kernel panic on resume from suspend. Only thing more you can do is try to capture debug logs with nvidia-bug-report.sh (I go in during a crash via SSH, usually the system is still responsive for a little while after), and post it to the NVIDIA Linux forums. They do actually seem to use the feedback there, NVIDIA reps respond from time to time and say they’ve submitted bug reports from the feedback. Otherwise, after that yeah you just do what you have to do for a usable system and wait…
