2.6.21-rc4 fails to start USB HCD NEC 720101 with MPC8349EMDS

Hello,

I have an MPC8349EMDS board with an 2.6.21-rc4 kernel and u-boot 1.2.0. I use the dts file from the kernel sources.

I've plugged a PCI board with a NEC 720101 (http://www.necel.com/usb/en/product/upd720101.html).
This chip is a USB Host Controller with 1 EHCI if and 2 OHCI if.

It looks like the kernel sees the USB if, but it fails to start it:

Could someone help me to understand these messages?
