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.

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.
