network unreachable after kernel build
I installed woody with the 2.2.20-idepci kernel last week, and yesterday
I built 2.4.18 from source using kernel-package. Now the network is
unreachable, even in ping. Honestly I have no idea what is going on.
Here's why. When I run dmesg, I get (only including network card items
for brevity):
natsemi.c:v1.07 1/9/2001 Written by Donald Becker <becker@scyld.com>
http://www.scyld.com/network/natsemi.html
(unofficial 2.4.x kernel port, version 1.07+LK1.0.14, Nov 27, 2001
Jeff Garzik, Tjeerd Mulder)
eth0: NatSemi DP8381[56] at 0xe0800000, 00:02:e3:16:ff:59, IRQ 5.
eth0: link up.
eth0: Setting full-duplex based on negotiated link capability.
The only difference from the old kernel is the "at" address. It used to
be 0xe08f0000. When I run ifconfig, I get:
george@rickety:~$ /sbin/ifconfig
eth0 Link encap:Ethernet HWaddr 00:02:E3:16:FF:59

I got the same output with the old kernel, except eth0 had an IP
address. One major difference in the kernels is that I built in the
network card driver -- does this cause problems? Any help is greatly
appreciated.
