Do you have a PS/2 keyboard and/or mouse attached to your computer? I reproduced similar output on my board with no PS/2 device attached. (I don't own any PS/2 keyboard/mouse so I can't test the other cases) It seems that the PS/2 controller is disabled on startup. When the i8042 kbd driver probes the KBD0 device _STA reports that the device isn't enabled. It then seems to read the I/O ports (which are uninitialized, so 0x00, 0x00) so it tries to enable it and either it fails or really enables it and reports a failure (I'm not yet sure about the reason, I couldn't find much info about error -16 yet). Anyway later when the aux driver probes PS2M it is enabled, so this one doesn't fail. Can you send the output from superiotool -d? I would like to see if there are really only zeroes in the keyboard controller IO port registers. > I also saw something that looks like bug in your code (my proposed > changes below).

I'll correct them. BTW, thanks for testing the code -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
