So you have a iic0 (dwiic) that is not properly working and the ihidev connected via that will not work (probably the touchpad). But the keyboard is plain old PS/2: [ 1.002535] pckbc1 at acpi0 (KBD, LEN0071) (kbd port): io 0x60,0x64 irq 1 [ 1.002535] pckbc2 at acpi0 (MOU, LEN0325) (aux port): irq 12 [ 1.002535] pckbd0 at pckbc1 (kbd slot) [ 1.002535] pckbc1: using irq 1 for kbd slot [ 1.002535] wskbd0 at pckbd0: console keyboard [ 1.002535] pms0 at pckbc1 (aux slot) [ 1.002535] pckbc1: using irq 12 for aux slot [ 1.002535] wsmouse0 at pms0 mux 0 and the pms0 should not be there, I wonder if the firmware has some method to switch between the native iic/ihidev mode and the pms emulation, and we should not try to attach both. My guess is that this needs some ACPI quirks. Martin
