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

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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu.

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. -- You

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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to

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

2017-02-03 Thread Jonathan Ganc
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.
