I've seen this before - not all PC hardware works the same :-)  The 
problem I observed had to do with resetting the IDE hardware.

Try disabling the IDE interface like this:
  % ecosconfig import no_IDE
  % ecosconfig tree
  % make

Where the file "no_IDE" looks like this (sans "---" lines):
------------------------------------------
cdl_component CYGPKG_REDBOOT_DISK {
    user_value 0
};
------------------------------------------

If that doesn't help, try adding some messages during the initialization
of RedBoot (in .../redboot/current/src/main.c)
