--- Comment #1 from Alex Deucher alexdeucher@gmail.com --- The bug title should be changed. The atombios messages are just a side effect of the driver trying to access a GPU that has been powered down via vgaswitcheroo.

--- Comment #2 from RussianNeuroMancer russianneuromancer@ya.ru --- So 3.13 trying to power down/up dGPU even if radeon.runpm=1 is not set? runpm is enabled by default?

runpm is enabled by default in 3.13.

--- Comment #4 from RussianNeuroMancer russianneuromancer@ya.ru --- Thanks for answer. From others reports related to runpm I assume it has to be enabled manually, but mistake. I tried to disabled runpm and now Linux 3.13 seems like boot fine, like previous releases. So this issue probably duplicate of this one: https://bugs.freedesktop.org/show_bug.cgi?id=62882
