Re: VDPAU nvidia: Error detected 0 5525
Can you please supply an nvidia-bug-report file so that we can see details of your HW.
Also, exactly what do you mean by suspend2ram/suspend2disk (historically, there have been a variety of ways that those features were implemented). Specifically, which Linux distro and version are you using, and how are you invoking suspend/hibernate (e.g. Gnome menu, running a specific command in a shell, etc.)?
Finally, is any VDPAU application running when you suspend? Or, does the issue occur if you quit all VDPAU apps, suspend, resume, then try to start another VDPAU app?
