Where exactly does U-Boot hang?

What are the console messages you see? And which U-Boot version is
this, and which version of the Canyonlands board?

This is inconsistent: above you report U-Boot hangs, here you claim
that Linux reboots?

Did you try running in another configuration, like 800-nor or
1066-nor?
