Full dmesg attached. I don't think I have debug symbols here, so no further
details at this time. It only happened after quite a while, so it's not easily
reproducable. Just putting it here because I haven't seen a report like this.

dmesg with stacktrace used for getting line numbers

With 4.7 it's still happening. I finally built a kernel with debug symbols
because on Intel graphics I also have something like this...

I assume people have looked at the functions, but maybe some line numbers for
the 4.7.0 release help.

It's not clear that those are both one and the same bug.
