Okay, we leave this 'decompressing' error for a moment.  I rebuilt
(mostly using default options from buildroot) a very small rootfs
image, 780k cramfs.  This time, it boots without the 'decompressing'
error message, I still can not login in.  It's same: whatever user
name I inputed, the getty restarted and I get nothing but another
prompt.

If you experts can not guess what's is going on here, I hope you can
tell me how to debug this kind of problem.  Tks.
