This is the dmesg output while acpi_module is loaded: Note the wrong allocation of the keyboard controller to the acpi bus! atkbdc0: <Keyboard controller (i8042)> port 0x64,0x60 irq 1 on acpi0 atkbd0: <AT Keyboard> flags 0x1 irq 1 on atkbdc0 atkbd: the current kbd controller command byte 0047 atkbd: keyboard ID 0x54ab (2) kbd0 at atkbd0 kbd0: atkbd0, AT 101/102 (2), config:0x1, flags:0x3d0000 psm0: unable to allocate IRQ When I disable the loading of the acpi module the keyboard controller is correctly attached to the isa0 bus.
