I am not sure if your image is using the AHCI interface or IDE
interface. It really doesn't matter, there is a problem to debug either
way. You need to find someone to debug using the Corsair F120 SSD, or
debug it yourself. Is the problem for powerup only or both powerup
and cold reset button?

I also have USB keyboard problems, but my problem is different. For
each key I press, it repeats a couple dozen times. I solve the problem
by adding a 'break' to usb-hid.c:

    for (;;) {
        struct keyevent data;
        int ret = usb_poll_intr(pipe, &data);
        if (ret)
        break; <==================

With this change, I am able to type well enough to get windbg started,
which is all I needed at the time. But typing is very sluggish. I
believe the sluggishness is due to use of 8254 periodic interrupt
polling to service the keyboard.
