Dmesg log - after third pass of piglit.
I was giving piglit a trial run, and noticed that there was a few errors about
the radeon driver being able to allocate gem objects.

Some piglit tests are about allocating as large textures as po= ssible, which can result in such intermittent allocation failures. It might be feasible to ha= ndle this more gracefully in userspace, but otherwise it should be mostly harmle= ss, assuming there are no other, real problems associated with it.
AFAIK, allocation failures are correctly reported to applicati= ons as the GL_OUT_OF_MEMORY errors.

Totally agree with that. Some piglit tests even allocate all t= he memory on purpose to test that the driver can handle that gracefully, and the expecta= tion in the good case is that those error messages start to appear. As long as you don't experience any crash, hang or something like this everything should be fine.
