Iirc your issue goes away with rc6=0, the residual bugs we still have
all still happen with rc6 disable, so probably something else. Hence
also why we're asking everyone who can still reproduce to try a
bisect, since with rc6 disabled we've can't reproduce the hang any
more (beforehand we could reproduce it on 3 different ilk machines).
The important part is to not enable rc6 (on ironlake at least) when
bisecting.
