It turns out to be an ACPICA regression not related to graphics at all.

As for this issue, I did not observe any more hangs with v3.4 or 3.5-rc, *yet*.
It is hard to tell for sure since it usually takes a while (sometimes hours)
for it to occure. Which makes it also almost impossible to bisect and to find
the commit that might have fixed it.

Cheers,
Stefan.
