Linux kernel - No init found error


I am trying to boot up rather a large root-fs of 21MB. After changing the root file system size, I could get the kernel to recognize the root file system at least, but it does not find init in it. Any ideas?
(I tried passing init=/sbin/init on the command line, but somehow that line is ignored by the kernel)

Here is the log:

did you boot from a recovery CD or a live cd and checked if there is really /sbin/init?
