Try cutting the vertexrate demo down to a minimal subset that causes the lockup
and trace the command buffer.
You're getting DMA_VTX_PROTECTION so you're likely accessing out of bounds
vertex data somehow.
If you can find the commands that cause it and compare with the gallium code
you might be able to find the error.

Attached patch for tracing command buffer (apply to libdrm).
