Problem with the AHCI driver

[Nobody III]

I suggest testing other hardware drivers (e.g. usb, nic, framebuffer), and
checking for issues and oddities. One thing I noticed is that usb_drv
wasn't detecting any input from devices plugged into my usb 2.0 ports, but
it worked fine with my usb 3.0 ports. nic_drv worked fine though.
