I had the same problem a month ago more or less. With a glibc toolchain 
built with crosstool-NG the init process was dying and the kernel 
panic'ing as a result because init (pid=1) was not supposed to die.

Unfortunately i could not manage to find what the problem was. All i 
found is that it was happening with some versions of glibc while it was 
working with other versions: glibc-2.9 was failing, so my workaround was 
finally to select EGLIBC-2.10 to build the toolchain. With that version 
it worked for me.

Give it a try to a newer version of glibc/eglibc (starting with 2.10) 
and let us know if it works.
