Re: [DRM] Lower the severity of the radeon lockup messages.

At the risk of sounding obvious, wouldn't it be better to enhance the driver to dump out more useful debugging info in this case rather than just suppressing the ABRT report?

In theory yes, in practice that is non-trivial. The amount of data you need to keep track off is in the MBs, it can range from any previous GPU command stream sent to the GPU, to the contents of any of the vertex buffers etc.

the problem with GPU lockups is you don't notice them until after you've queued up a tonne more stuff since they are such deep pipelines.
