no route for lo interface!!

[Ferenc Kiraly <feri@fiz.uni-lj.si>]

	Hi!

I've just upgraded my kernel to 2.2.1. Now I cannot
add a route for the loopback interface:

fire:~# route add -net 127.0.0.0 dev lo
SIOCADDRT: Invalid argument

As a matter of fact, I cannot add a route for any 
interface (same error). Inspite of this I do have routes
for the two network interfaces in my routeing table:

fire:~# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
195.250.214.64  *               255.255.255.192 U     0      0        0
eth0
tribe           *               255.255.255.0   U     0      0        0
eth1
default         robin.arxel.si  0.0.0.0         UG    1      0        0
eth0

I cannot figure out where these routes are added, but
I get them even if I comment out the appropriate lines in
/etc/init.d/network.

How do I get this working?
