Cannot bring up lo.

[Matthieu Paindavoine <mpaindav@arinc.com>]

Hello,

I have had this error for about 2 days....
I can't bring the loopback interface. If I type 
'/etc/init.d/networking restart', I get:

Reconfiguring network interfaces: lo: unknown interface: Bad file descriptor
SIOCSIFADDR: Bad file descriptor
lo: unknown interface: Bad file descriptor
lo: unknown interface: Bad file descriptor
done.

'ifconfig lo 127.0.0.1' will give me
lo: unknown interface: Bad file descriptor

but 'ifconfig' reports eth0 correctly.

So I don't know what's wrong...
Is this a /dev/xxx screwed up, is this a kernel config pb, is this a
/etc config pb ?? 

Any suggestion appreciated.

Thank you,

Matthieu
