Just put ubuntu 14.04 on my HP 15.6" AMD A8 2.0GHZ quad-core laptop and am experiencing random freezes (need to do a hard shut-down/restart, no mouse or keyboard functionality during freezes). There seems to be nothing I can do to replicate the freezes and sometimes I can go hours without one, other times it will only take a few minutes after booting.

I have tried re-installing multiple times to no avail. Also tried switching my drivers but anytime I try to switch via the system preferences tab the computer automatically switches back to the recommended driver.

A few more details about the computer:3.3 GiB of memory, AMD A8-6410 APU with AMD Radeon R5 Graphics x4 processor. For graphics running Gallium 0.4 on AMD Mullins.

Does it happen when you are browsing in Firefox?

I have the same problem as well. It only seems to occur when I am browsing in FireFox and do some rapid moving around of the pages.

Also, I installed fresh Ubuntu 14.04 LTS and get a slightly different reaction. Instead of staying frozen until I reboot the computer, if I wait ab out 5 minutes, it goes to the log-in screen. Of course, I just remember that when it happens, before waiting, I give it a 3-key salute and leave it alone after that.

Maybe that's the escape, but not the solution.

I'm using Nvidia graphics, so I guess you just ruled out the graphics driver being the culprit.

This happens to me too I have the same cpu WTF? Nobody has an answer? I tried re installing 3 times same thing. At first I though it was firefox but then it froze when I was using Xbmc and then chrome it happens randomly. I also noticed that it gets hotter than windows 8 so I installed powertop it the temperature felt cooler but it still froze on me. I also left it for 6 minutes doing nothing but nothing happend the only thing that responded was my wifi being turned on and off but that's it couldn't open a terminal or nothing.
