I suspect I can live with that for now. The lockdep one looks like it's mainly an initialization issue, so you'd never get the actual deadlock in practice, but it's obviously annoying. The intel_pm.c one I'll have to defer to the i915 people for.. I'll be travelling much of this week (flying to Finland tomorrow, back on Sunday - yay, 30h in airplanes for three days on the ground, but it's my dad's bday), and my internet will be sporadic. But I'll have a laptop and be able to pull stuff every once in a while. It would be good to have this one resolved, and I just need to worry about the remaining VM problem..
