The kernel is rejecting your command stream as invalid.  The command stream is
the stream of register writes produced by the 3D driver based on the GL state. 
The bug is either in the drm command checker in the kernel or in the mesa 3D
driver.  The error in your dmesg is saying that the Z buffer is enabled in the
command stream, but that there is no buffer associated with it.  I would guess
perhaps ZB_CNTL (0x4F00) is not getting emitted as part of the command stream.
