It looks more like a user space issue. If the kernel reports the
headphone status as unplugged when they're not, then that's a kernel
issue, but I didn't spot any jack status differences in the diff you
posted. You could report[1] a bug on PulseAudio (if you're using it),
and include a "pactl lsit" diff between working and not-working state.
