I am building my initrd using cpio -H newc -o| gzip -9 -c - > initrd.gz I do not activate the a ccwgroup device because I thought it was done for you automatically by udev. I turned udevd into a daemon in my init script, but I do not see the network devices online.
The output of lsqeth and lscss are:
sh-3.2# lsqeth
grep: invalid option -- m

How exactly are you building your custom initrd? Does your custom built
initrd create and activate a ccwgroup device according to Chapter 7 in
http://public.dhe.ibm.com/software/dw/linux390/docu/lk33dd05.pdf? (post
the output of lsqeth). Are all required ccw devices available to Linux?
(post the output of lscss).
