That report is against the 4.8 kernel, which is not a supported kernel
since a while. Since your system(s) has been upgraded many times, and it
should be good to report about right actual config, instead of adding
comment on that one.
So closing that report.

I'm unable to boot latest kernel after upgrade to 16.10, It's just hangs with
no disk activity, all latest updates where installed using 4.4.0-59 (it boots
properly) but no luck.
I also tried latest nouveau, latest available nvidia driver from
That driver made it so I could no longer start X. So neither kernel
