You're too fixated on ATOM BIOS. :) It's mainly used for things like
modesetting, not for 3D rendering.

There's no sign of a GPU lockup or anthing like that in the files you attached,
so what exactly are the symptoms?

Assuming the problem is that the DOTA2 process itself crashes, we'll need to
see a gdb backtrace of the crash or at least the console output corresponding
to the crash.
