## Discrepancy

AIRCRAFT WAS NOT GROUNDED: ABOUT 1.5 HOUR INTO FLIGHT, AURAL WARNING AND MESSAGE "SMOKE UPPER RESTF4" CAME ON, FOLLOWED SHORTLY AFTER WITH "CARGO HEAT BULK" ECIAS. NO EVIDENCE OF SMOKE AT ANY TIME. BOTH LIGHTS EXTINGUISHED SHORTLY THEREAFTER AND NORMAL REMAINDER OF FLIGHT. REPLACED OVERHEAD FLIGHT ATTENDANT REST EXHAUST SHUTOFF VALVE PER DMC B787-A-21-29-11-00A.
