udhcpc: sendto: Network is down

I've been working with a buildroot-2009.02 environment that I built for a TS-7400 board (uses a 2.4 kernel) quite successfully for several months now. So far I've been configuring the board's network settings manually using ifconfig and route.

Recently I tried to start using DHCP, but udhcpc is not happy about something:

# ifconfig eth0 up
# ifconfig eth0

eth0 Link encap:Ethernet HWaddr 00:D0:69:40:7C:D6

UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX packets:51 errors:0 dropped:0 overruns:0 frame:0

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:1000

RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)

Interrupt:39

# udhcpc -i eth0

udhcpc (v1.13.2) started

Sending discover...

udhcpc: sendto: Network is down

Sending discover...

udhcpc: sendto: Network is down

I've verified the network is actually up (all the lights are on). If I configure an IP address manually it works fine, e.g.:

# ifconfig eth0 192.168.1.30 up

# ping 192.168.1.1

PING 192.168.1.1 (192.168.1.1): 56 data bytes

64 bytes from 192.168.1.1: seq=0 ttl=64 time=0.000 ms

64 bytes from 192.168.1.1: seq=1 ttl=64 time=0.000 ms

64 bytes from 192.168.1.1: seq=2 ttl=64 time=0.000 ms

--- 192.168.1.1 ping statistics ---

3 packets transmitted, 3 packets received, 0% packet loss

round-trip min/avg/max = 0.000/0.000/0.000 ms

What could I be missing?

Thanks
