Indeed, this _is_ off topic here.

Well, I think that the DULG shows this a bit differently, doesn't it?

Why are you writing "IP=" when all available documentation has "ip=" ?
Why are there so many colons in your argument? 

Documentation/nfsroot.txt says:

ip=<client-ip>:<server-ip>:<gw-ip>:<netmask>:<hostname>:<device>:<autoconf>

Will you please compare this with your string?

-> grep 101 /usr/include/*/errno.h
/usr/include/asm/errno.h:#define        ENETUNREACH     101     /* Network is unreachable */

Read: Network is unreachable

Blame it on yourself for being unable to  copy  and  paste  from  the
available documentation.

Best regards,

Wolfgang Denk
