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.
