It turns out that 3.4.8 didn't use the i8042 keyboard device anyway: >>From 3.4.8: ... i8042 aux: probe of 00:07 failed with error -16 i8042: PNP: PS/2 Controller [PNP0303] at 0x60,0x64 irq 1 i8042: PNP: PS/2 appears to have AUX port disabled, if this is incorrect please boot with i8042.nopnp serio: i8042 KBD port at 0x60,0x64 irq 1 mousedev: PS/2 mouse device common for all mice TCP: cubic registered Registering the dns_resolver key type Using IPI Shortcut mode Freeing unused kernel memory: 268k freed Write protecting the kernel text: 1628k Write protecting the kernel read-only data: 580k input: AT Translated Set 2 keyboard as /devices/platform/i8042/serio0/input/input0 ... Hence adding the i8042_nokbd=1 parameter merely forces the kernel to do again what it used to do automatically.Does anyone have any theories as to why the 3.5.x kernel now needs help to set the keyboard up correctly, please? Thanks, Chris
