Thanks, It sounds like you have more than one machine with similar
quoted
problems. Can you collect the log from the other machines with 4.8-rc8?

and also a boot log with 4.6 kernel where things are working?
The attached logs are from another machine:

dmesg-bad-debug.txt: 4.8-rc8 with your debug patch - bad

dmesg-reverted.txt: 4.8-rc8 with patches (as per Rafael's suggestion) 
reverted - good

dmesg-3.6.txt: 4.6 (Debian kernel) - good
I think I see a race condition for the SCI interrupt. I need another dump from
4.8-rc8 with the attached patch to confirm. Let's remove the previous one and
apply this one.
