Bug#818467: (linux-image-4.4.0-1-amd64: Kernel oops after disconnecting an external USB disk)
Hello,
I performed several tests on the subject of this bug and I found out
that it happens only if a use a specific USB disk. It doesn't show if I
use another USB device such as a pen drive or a different disk and it
doesn't show if I don't run X11.
When I use the USB disk responsible for the kernel oops, while not using
X11, this is what I find in /var/log/syslog:

I'm using an nvidia driver for my GeForce GTS 450.
I hope this might help.
