Any time someone messes with the clock timing code, they always break Sparc. We have to make assumptions about several things, one of which is the clock crystal used because the Sun firmware provides no way to just guess this so we just have to know what it is. Second, as you mention we reverse calculate the clocks to turn the video mode the firmware brought the card up in into the parameters the driver wants. Please, can we revert your changes if we can't fix Sparc quickly? This is a pretty serious regression you've added and I have this feeling it's going to stay broke for some time as you go back and forth with us trying to resolve this. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
