__DmacDoState and __UsbCamDoState existed but weren't in the module list, so the memcpy deadline and camera state carried over from before a load. The NpDrm licensee key wasn't saved or reset at all, so EDATA opened after a load in a fresh session couldn't be decrypted. Co-Authored-By: Claude Opus 5.5 (1M context) <[email protected]>
