There are two vmlinux.lds files in the linux-2.6.x directory. The file in the arch/nios2/boot/compressed does not have the .init.ramfs reference. The file in the arch/nios2/kernel does have the .init.ramfs reference.

No filesystem could mount root, tried:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Of course, your downloaded program does not contain the 'root file system'. Maybe, your linking process causes these errors.
