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.

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.

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:
