Hello all
I have a rather vanilla little 7400 system that I am attempting to follow the
docs to get the 2.6.21 kernel compiled and running on. I actually am having no
problems with the kernel itself, but am having no luck with either NFS or a
custom initrd for the root file system.
It appears like I do not have a init parameter configured in the kernel command
line OR like I don't have my inittab respawn directive set correctly for the
ttyAM0...?
Does anything below stand out for anyone?

It appears to find and uncompress the initrd, and I don't see any more output
so I believe it doesn't encounter any errors with that uncompression...??
My inittrab is the following (to allow busybox serial port access):
1 ::sysinit:/etc/init.d/rcS
2
3 ::askfirst:-/bin/sh
4 tty2::askfirst:-/bin/sh
5 tty3::askfirst:-/bin/sh
6 tty4::askfirst:-/bin/sh
7
8 ::respawn:/sbin/getty -L ttyAM0 115200 vt100
9 ::respawn:/sbin/getty -L ttyAM1 115200 vt100
----
Busybox is syn linked for my /sbin/init:
lrwxrwxrwx 1 root root 14 2010-04-14 23:27 init -> ../bin/busybox

Any thoughts?
