Not for me on my GeForce 8500 GT, and I still cannot suspend more than once, subsequent attempts fail:

Interesting. Were there any messages prior to that?

I guess the the fifo code detected a timeout when trying to save the graphics context, I have I have other patches in my tree (I'll push them soon, tied up with other work atm) that might help here.
Thanks, I'll try them when they are available.
With current nouveau master ("drm/nouveau: fix find/replace bug in license header") suspending works again, thanks! However, it is a bit slow, taking between two and five seconds:

With the 3.4.8 kernel, suspending takes little more than one second.
Cheers, Sven
I confirm exactly the same thing.
Here suspend takes more that 10 seconds:

In my case suspend also takes longer than usual, in the order of 10 seconds.
@Ben: Have you been able to reproduce this?
