3.8-rc2: EFI framebuffer lock inversion...
On 3.8-rc2 with lockdep enabled and dual-GPU setup (Macbook Pro
Retina), I see two releated lock inversion issues with the EFI
framebuffer, leading to possible deadlock: when X takes over from the
EFI framebuffer [1] and when nouveau releases the framebuffer when
being vgaswitcherood [2].
Let me know if you'd like any testing or analysis when I can get the time.
Many thanks,
Daniel
