That's what I suspected. So I just installed the latest HPS usb stack 
and it's the same.

pcm0: <nVidia nForce4> port 0xdc00-0xdcff,0x4400-0x44ff mem 
0xd5003000-0xd5003fff irq 23 at device 4.0 on pci0
pcm0: [ITHREAD]
pcm0: cannot reset channel 0
pcm0: unable to initialize the card
device_attach: pcm0 attach returned 6


With the latest HPS USB stack not sure if that's the same one in HEAD or 
not.
Maybe something is conflicting or some other change has caused the 
resources to be tied up. That's a really rough guess with no evidence to 
support it.
