[Nouveau] nouveau: kernel rejected pushbuf: Invalid argument

Thu Apr 21 16:43:25 UTC 2016

If you (or Java, behind your back) is using an indirect draw, that
could explain the failures - I only got those "fully" right fairly
recently. These, and a few other matters, should be fixed with a more
recent mesa version - 11.2.1 was just released, I'd recommend trying
with that.

Another simple explanation is if your application is multithreaded and
is drawing concurrently from multiple threads -- this is plain
unsupported by nouveau. (Even though it can be done in ways that are
perfectly legal in GL.)

You could try to make an apitrace
(https://github.com/apitrace/apitrace/) to see what's actually going
on deep down inside. But do that after you update mesa.
