Radeon: Failed to allocate a buffer

The following error occurs when running the game with shadows set on Ultra with RadeonSI Mesa drivers.

Re: Radeon: Failed to allocate a buffer

Nothing anywhere in the game allocates a buffer of that size. The shadow atlas is actually only 4096*4096*2bytes/pixel (GL_DEPTH_COMPONENT16 texture of 4096x4096) in size. The bug is therefor in Mesa. Looks like they have some internal overflow issue. Please forward the issue to them.
