Looking at the disassembly, 'n' is 2 and 'segments' is 0xffff.
Is this still a problem if you don't use an IO scheduler? With deadline, I'm not finding any path to bio_attempt_discard_merge which is where the nr_phys_segments is supposed to get it set to 2. Not sure how it could becmoe 0xffff, though.
