--- Comment #2 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Perhaps an interesting resource for you:
http://nouveau.freedesktop.org/wiki/Optimus/

I'm no expect in the matter, but I'm pretty sure that you shouldn't
be using
vgaswitcheroo in conjunction with the new runtime pm stuff. Try disabling it
(vgaswitcheroo). Alternatively (or in addition to), try disabling the new
runtime pm logic, perhaps it doesn't work correctly for you.

Is this a new issue? IOW, did this work properly on older kernels? If so, and
the above fails, a bisect may be in order.
