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. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch
