Hi..
This ORA-600 refers to a mismatch has been detected between Redo records and rollback (Undo) records.Is better to lock a call with oracle support.Secondly, apply latest patch on the DB.
I had expereiced the same error, but my DB was in open mode, so i created a new undo tablespace and changed the undo_tablespace parameter and it worked.
