Re: "[mi] EQ overflowing. The server is probably stuck in an infinite loop."
When it happens again, could you ssh into your system and run "nvidia-bug-report.sh" to capture a snapshot of the system state at the time of the issue? I would have done that, but I did not think of it at the time. I imagine that a snapshot at the time of the incident would be more helpful to Nvidia in fixing this than a snapshot after xdm has been restarted.
