Hi I just noticed that the keyboard will not work on boxes which have a usb device connected during boot. The i8042 driver will fail to init during boot: Can't read CTR while initializing i8042. We have a contract with HP and it seems to affect (at least) all HP computers we have. Possible workarounds are to replace the usb mouse by ps/2 one or to boot with acpi off. The old HP series workes with SL4.1, but the new one's require SL4.2 for the NIC to work;-( Gerald PS: Is turning acpi off expected to have sideeffects (other than PM not working - which is no big deal for a desktop).
