How about posting in detail the kernel messages just before the crash?
What are the contents of that nfs-root (which distribuition)? Since you
get to the init message, I presume it is mounted OK by the kernel? What is
the set of boot line parameters you use for that floopy kernel?
Are you using DHCP to configure the network? Can you diff the kernel
configuration files for 2.2.20 and 2.4.19 to check the differences? One
funny thing I remember is that in the 2.4 kernels you must turn on the
dhcp option in the kernel-level autoconfiguration section even you are not
actually going to use it...
