Narrative:

I was in first class galley and heard a banging noise out in first class. I went to check it above the first class credenza. I quickly ran up to cockpit and said, 'somebody's got to come listen to this noise.' pilot came out and just then all flight attendants on break (3) flew out of crew rest due to smell of plaster in the cabin. Purser began climbing the ceiling, feeling for heat in aft first class/business class galley in crew bunk and pilot came back out to wake him. Purser instructed us to get all halons and personal breathing equipment and put them on first class credenza. We were told we were headed for boston -- 45 mins away. The pilots turned off a pack and fixed the problem. I never saw smoke in the cabin. I heard a very loud noise in the ceiling in aft part of first class and smelled a strong plaster smell. Smell dissipated. Landed in bos to check plane. Supplemental information from acn 418453: flight attendant said we have the smell of an electrical fire throughout the business class cabin. We grabbed the halon and personal breathing equipment and proceeded to business class to search for the source of this odor. After captain turned off air conditioning pack, the smell dissipated.
