If that's the issue, I assure you nowadays you can hit it quite reliably, at least on my iBook G4. (Which, by the way is also hanging randomly on 5.7-rc5, for apparently unrelated reasons; I haven't bisected yet, but fortunately I can do it on the G5 while keeping what's left of my sanity.) _______________________________________________ dri-devel mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/dri-devel
