It turns out that there are a 2 separate issues with this netbook that needed fixing 1) The touchpad requires the equivalent of "i8042.reset", which resets the controller before probing. (This is done via a DMI quirk in patch 2/2) 2) About half the time, the reset will fail the first time. In the current code, this is fatal and then also disables the keyboard in addition to the touchpad. Ungood. Patch 1 makes the kernel retry the reset upto five times before giving up (it seems the 2nd or 3rd time succeed for me), and also adds an option to not make such a failure fatal to the keyboard. I don't think this is a regression, but it is pretty nasty behavior (the machine is useless without) so it could be a 2.6.29 candidate... -- Arjan van de Ven Intel Open Source Technology Centre For development, discussion and tips for power savings, visit http://www.lesswatts.org -- 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/
