The OR routing logic in NVKM does not expect to receive supervisor interrupts until the DD has provided consistent information on the ORs it's using and the EVO/NVD assembly state to match. The combination of changing window ownership + core channel update during display init triggered a situation where we'd disconnect an OR from the pad it was meant to still be driving on some systems.
