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:
