Below, after the uname, aplay, arecord, amidi and amixer output, the
qjackctl messages up to the point where I do get sound with guitarx in
kernel 3.18.9 and I don't with kernel 4.0.5 are listed.
if I switch jack to PCH, audio play and record works with both kernels.
Anyone else have a problem with Focusrite Scarlett and kernel 4.x ?
Should I submit a bug report, if so, where?

I don't see any difference with alsamixer,
pulseaudio and jack
settings, and input works with both.
You're using the same settings, by most likely running the same audio
sessions, ok, but are you getting the same jackd messages too?
The output of aplay -l;arecord -l;amidi -l is equal too?
amixer >> Desktop/linux_v3.txt
amixer >> Desktop/linux_v4.txt
No diff?

"Essentially"? Is there any difference in the mixer setting?
The difference is the order of the cards,
HDMI, PCH, USB in kernel 3.18.9 and
USB, HDMI, PCH in kernel 4.0.5
A setting like this in /etc/rc.d/ should result in the old order:
options snd slots=snd-hda-intel,snd-hda-intel,snd-usb-audio
Does it work with aplay? ("aplay -D plughw:USB something.wav")
