--- Comment #4 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Unfortunately nouveau doesn't do well with concurrent multi-threaded GL usage.
The PBDMA errors, I believe, may be indicators of something like that.

I believe plasma added some logic to avoid doing that, at least on top of
nouveau (or perhaps that was Qt).

There's also some pending work to improve the multi-threaded situation for
nouveau, but that won't do you much good on a year-old version of mesa.
