AC Power Unigine Heaven dmesg
I have a Dell laptop with an Intel iGPU and a Radeon dGPU (a Firepro W5130M, recognized as a Radeon HD 8830M by lspci).
Whenever I attempt to use the Radeon card via DRI_PRIME=1 while the laptop is plugged in, the card crashes. When on battery the card performs fine.
One way I have tested this is with glxgears. Often glxgears will work the first time it is run, but if it is closed and then opened a few seconds later, it will crash.
I have also tried running programs like Portal 2 and Unigine Heaven. These always hang. Unfortunately the error messages produced in dmesg are not the most consistent. Sometimes I get a backtrace, sometimes even a kernel panic on reboot.
I'll post the various logs I have. One thing I have found is that glxgears does not crash if I use radeon.runpm=0, however it still hangs when running something like Portal.
