I did the test, and addded the content of /proc/interrupts. https://paste.ubuntu.com/25312443/ As you can see, after "[INSERT HEADPHONE]", we only get "mbhc switch irq", but not "mbhc btn press irq". Let me know if you need more details. As I said before, I don't see that 100% of the time, but I don't do anything special to trigger it either (like pulling the cable extra slowly or whatnot), it just happens.
