First of all, I hope you don't mind that I'm including my mom here, so that she can follow how her computer is doing, or, rather, what I am doing with her computer.
To start that I suggest you try to compile kernel 4.4 by yourself first.
That should also yield a temporary solution until we can narrow down the root cause.
I tried using Ubuntu's unpatched/precompiled kernels 4.2, 4.4, 4.8, 4.10 and 4.11-rc5 and, apparently, they now always show this message *and* it frequently freezes to the point that no magic Sysrq keys work, sometimes the caps lock kernel blinks and so on.
Booting with radeon.modeset=0 allows the computer to boot to the desktop environment, but makes the CPU so hot when she plays her flashplayer-based games that the kernel shows many messages of thermal limit being reached and CPU speed being throttled.
Booting with radeon.runpm=0 still gets me all the error messages listed in the subject (and present in the logs that I sent to bugzilla), but the temperature *seems* to be slightly lower (not enough testing was done with this configuration).
I don't know how to see/check what GPU is being used at a given time: if the Intel GPU or if the AMD GPU...
So, given that the problem now seems to be present with all those kernel versions that I tested, is it worthwhile to compile my own kernels?
As before, I will try to do whatever I'm directed to.
Thanks a lot,
Rogério.
