Speaking of hangs - yes I'm noticing recently significant problems with suspend resume - but usually the scenario:

suspend undock home/resume dock work/suspend dock work/resume undock home works.
(with 1 per week failure - see my recent lkml post:
https://lkml.org/lkml/2012/11/15/369
unsure wheather it's related or not)

However if I try multiple suspend/resume in dock - it doesn't take long
to experience black-screen death.

Unfortunately also my 'serial line' debugging now fails since after resume I get just garbage on my serial line. But currently I do not have much free time to play with all this.
