Possible IOS image corrupted or checksum problem during the last IOS image upgrade. Get a new working IOS image, reboot the router and interrupt the boot process. You will be in rommon mode, load the new IOS image from there.
Since you will be using Xmodem to upload a new working IOS image. If possible, get the smallest size IOS image first for faster upload. You can upload your desired IOS image (or bigger size) once you succesfully booted from a new/smaller IOS image.
I think we have seen this as well. what type of cards are in the router? take out the modules and boot and see how long it takes then put the modules back in one at a time and see how long it takes. I think it is something to do with checking the cards.
