It's the opposite, the DRI device needs to be accessible to users that should be allowed to use it. You could create a 'drm' group and make the device node be owned by group 'drm'. You could make the device node mode 666 and allow access to everyone. Obviously such users have control over the GPU and thus the current desktop session (of any other user). That's why it is best practice to have access restricted. If the system crashes when you allow access, this means that the DRM code is buggy....
