Latitude 3150 random crashes

---

My laptop (Latitude 3150) is having issues. It's supported according to here and it doesn't have the slow resume issues either. I've tried multiple BIOS versions up to A04 I believe.

However, what it is doing with Ubuntu Gnome 14.04 and 16.04 installs (freshly updated, and for what it's worth, Fedora as well) is freezing up at completely random times. It seems to be regardless of the load it's having. I can't switch over to another console either, I have to forcefully shut it down and start it again. Doing some searching has some talks on disabling Bluetooth support but also recent keels not having the issue anymore, which I believe I have.

(For what it's worth, Windows is ruing 100% stable, also under higher load situations, so likely I can rule out any heat issues).

Would anyone mind giving me a hand looking for clues? Normally I do know quite well where to start but I honestly don't have a clue on where to start this time
