Odd behavoiur of one machine - radvd failing?

[Tony Hoyle <tmh@nothing-on.tv>]

I have 4 ipv6 enabled machines on a 6/4 tunnel.  3 of them work fine, 
but the 4th refuses to pick up an ipv6 address except its local one.

Route table on non-working machine:

fe80::/10 dev eth0  proto kernel  metric 256  mtu 1500 advmss 1440
ff00::/8 dev eth0  proto kernel  metric 256  mtu 1500 advmss 1440
default dev eth0  proto kernel  metric 256  mtu 1500 advmss 1440
unreachable default dev lo  metric -1  error -101

Route table on working machine (otherwise identically configured):

2002:d5d0:6371::/64 dev eth0  proto kernel  metric 256  expires 
2591514sec mtu 1500 advmss 1440
fe80::/10 dev eth0  proto kernel  metric 256  mtu 1500 advmss 1440
ff00::/8 dev eth0  proto kernel  metric 256  mtu 1500 advmss 1440
default via fe80::260:52ff:fe03:3654 dev eth0  proto kernel  metric 1024 
 expires 1314sec mtu 1500 advmss 1440
unreachable default dev lo  metric -1  error -101

I've been unable to get radvd to tell me exactly what the problem is... 
I've tried rebooting, leaving it on overnight, all sorts of things.

Both machines are connected to the same router and on the same subnet.
/etc/network/interfaces is identical on both machines (except for the 
different IP address).  There are no error logs generated that I can find.
