Problem with USB on S3C2412

Hi,

I'm having a strange problem with a USB host controller on my board with 
a S3C2412.
This board uses the USB port 1, initialized to host. On my machine_init 
code I have:

    s3c2410_modify_misccr(S3C2410_MISCCR_USBHOST |
                  S3C2410_MISCCR_USBSUSPND0 |
                  S3C2410_MISCCR_USBSUSPND1,
                  S3C2410_MISCCR_USBHOST |
                  S3C2410_MISCCR_USBSUSPND0);

I have a RTL8150 USB to Ethernet controller that I use to NFS root. If I 
boot my board passing no info on the Flash chip to kernel, all is OK:

but if I pass the MTD partitions info in the kernel parameters, the USB 
does not work OK and I'm not able to boot my board because the
