I'm using a nc8430 laptop and there are two big problems (haiku build 35629): - The internal keyboard and synaptics touchpad doesn't work at all. Both are attached by PS/2. An external USB keyboard and usb mouse does work. - After shutting haiku down the machine is in a "bad state" described on http://www.gentoo-wiki.info/HP_Compaq_nc8430#Noticed_ACPI_Issuses: "The systems stays in BIOS for about 30 second before proceeding next to boot the operating system. This is called "bad ACPI state" and you can only get the system from this state by turning the machine off and even removing the batery for a while." This issue has been fixed in linux by this commit: {{{ commit a1cec06177386ecc320af643de11cfa77e8945bd Author: Dmitry Torokhov <dtor@xxxxxxxxxxxxx> Date: Sun Feb 18 01:40:24 2007 -0500 Input: psmouse - properly reset mouse on shutdown/suspend Some people report that they need psmouse module unloaded for suspend to ram/disk to work properly. Let's make port cleanup behave the same way as driver unload. This fixes "bad state" roblem on various HP laptops, such as nx7400.
