mpc823 scc2 as eth0, nfs slow with linuxppc-2.4.25, but ok with linuxppc-2.4.4, why?

[Alex Zeffertt]

Your .config has probably changed when you upgraded your kernel.  It may be that
you've lost NFS v3 support and it's falling back on v1 support.  Check you have
v3 configured.  You need

CONFIG_NFS_FS=y
CONFIG_NFS_V3=y
CONFIG_ROOT_NFS=y
