The reason is chroma deblocking which is using q4 without pushing it to stack. :/
Unfortunately I am in Geneve this week and don't have ARM linux board with me so it is not easy to test.

Mickael Raulet: maybe guys at INSA could run tests this week if I make a fix? Could you ask?

I also have SAO, qpel and epel NEON patches for latest FFmpeg. They pass fate-hevc on Jetson TK1, but should be iOS and clobber checked.
