The ALTER PARTITION and SELECT seemed to be deadlocked when having innodb_thread_concurrency = 1. Problem was that there was unreleased latches in the ALTER PARTITION thread which was needed by the SELECT thread to be able to continue. Solution was to release the latches by commit before requesting upgrade to exclusive MDL lock. Updated according to reviewers comments (3).
