root nfs boot problems

[Stephan Ruettiger (r0337c)]

Hello Simon,

i have actually the same problem as you have in NOV 99 (showing below),
but i don't find the answer to your problem in the mailinglist-archive
(linuxppc-embedded). So i hope you can tell me how you have solved this
problem. I use a 2.2.13 kernel with math emulation.
The same configuration with the old kernel (2.1.119 - no module support)
works fine.
