I just tried again to test if nvidia updates would fix this ugly bug. In
summary: no.
I also tried the graphics-drivers ppa mentioned (specifically tried the
340 and 390 drivers) with the same negative results.
The only working solution for my nvidia-prime laptop (nvidia+intel) is
using
An *addition* to the workaround suggested by the original poster, for my
use case I disabled the autosuspend feature (that causes the reset
according to the logs). This seems to work fine around the problem:
# echo -1 >/sys/module/usbcore/parameters/autosuspend
With this option, I don't longer
I spoke too soon.While on my Ubuntu 16.10 laptop there hasn't been any
usb reses, the problems still persist on the 16.04 NUC when booted
through a 16.10 live session:

I just plugged in the drive into my laptop running Ubuntu 16.10 and
there are no reset with the drive and no workaround needed.
$ lsb_release -a
No LSB modules are available.

The workaround from above kind of works as making a USB3 drive usable,
but it's certainly not a solution, becase the reset still happen and the
IO interrupted.
I listen to music with rhythmbox On Ubuntu 16.4.1. My FLAC collection in
on an external USB3 disk. Every 9 minutes, there is a usb reset
This bug is so annoying because of the design of the keyboard backlight
in a lot of Dell laptops (incl mine, 7537): in daytime the backlight
make keys unreadable (they are painted grey with the character in
transparent plastic). It is even annoying even when you type blindly:
you automatically try
Workaround for me is returning to the previous acceleration setup (uxa
instead of sna):
$ cat /etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
Identifier "Card0"
Driver "Intel"
Option "AccelMethod" "uxa"
EndSection
I added that file, restarted X and no more crashes and better video

The crash is also triggered using a Live CD/USB, you just need to wait
enough while keeping /var/log/syslog open.
I think the bug is triggered sometimes by applications using 3D. In my
case, virtualbox is the nr 1 application trigging the crash (not
everytime, but kind of often).

For people hit by this bug, looking for a workaround:
I reverted to the latest Ubuntu kernel from 15.04. It was still on my
boot menu (my system was upgraded). The packages can be downloaded from
here: http://packages.ubuntu.com/vivid-updates/kernel/
This is installed on my system:
me@this:~$
I noticed this syslog output just before the crash:
