My first step was to simply restore the behaviour to 2.3.36 and then look for an alternate patch. I'd like to give any such patch at least the chance for smoketesting by QA (and the machines here) before asking Linus to pull ;-) There is one interesting difference between the BIOS and KMS clock setting for the Lenovo U160; the BIOS is able to set n=1, whereas we can't find a suitable clock with just a single wire. Maybe we can fix the U160 and save 0.1W as well! As far as I am aware, only the LVDS panel on the U160 is broken. Does anyone else have a panel that sprang to life (ignoring the recent bug) by disabling SSC? -Chris -- Chris Wilson, Intel Open Source Technology Centre -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
