Which version of Ubuntu are you using? Did you try the magical incantation I
listed in my initial post? I am currently using 16.04. There was a few days
(maybe 2 or 3 weeks ago) when the problem reappeared but it disappeared again.
I thought it might have been related to a new kernel version but
I will try when I get a chance but I am busy for at least a few days and
this is my main computer so I can't afford to muck around with it too
carelessly.

There are definitely at least *some* BIOS problems with the 5470. For
example, it seems to have clock speed issues (where the CPU clock speed
will stay between 400 MHz - 800 MHz) which I have to resolve using
either `wrmsr -a 0x19a 0x0` or `cpupower frequency-set -g performance`
or both.

Weird, right? I'm fairly content with my Dell but I think there are some
Linux-related BIOS issues. I'm glad that 1) this fixed your suspend
issues, 2) that I'm now sure that I'm not crazy.

So, a strange thing happened. In order to mitigate the problem, I
decided to switch to having the computer hibernate instead of suspend (I
outline below the steps I did to do that). And then, on a whim, I tried
suspending again. And it stopped crashing, even after I switched back to
suspend complet
I also can confirm the symptoms. Just to clarify one thing:
The problems occur with a 16.10 guest but disappears if I revert back to a
16.04.1 guest.
I am using a Ubuntu 16.10 host.

Public bug reported:
To generate the crash:
1) Suspend the system (e.g. choose suspend from the top menu).
2) At any point, unplug the cord (the bug happens if I unplug at any point
after suspend, even if I then replug before I resume)
3) Try to resume (pressing power button). Computer reboots.
