[Nouveau] [Bug 61765] Regression: null pointer dereference on reboot after switcheroo use

https://bugs.freedesktop.org/show_bug.cgi?id=61765

--- Comment #2 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Can you explain what steps you take in order to make this happen? It seems like
vgaswitcheroo turns off the nvidia card, and then Xorg sends it an ioctl (which
I would have assumed should fail) which breaks since the card is off.

still a problem with newer kernels (3.17, 3.18)? there were really many fixes
in between that could fix this...
