Originating where?

One unusual consequence of rebooting the inflight entertainment system whilst... inflight. Apparently our flight originated from somewhere mid-Atlantic.

Why would the originating point be lost? Wouldn't that be stored in non-volatile memory, indexed by flight number?

The Aer Lingus IFE is Linux-based, lots of complaints output to the console during boot about non-existent devices. Very untidy!
