Chilli dhcp problem (No such device or address) does any one heard?

Sat Jan 5 00:35:03 UTC 2008

Problem was a missing bridge interface. I couldn't regenarate the 
problem in a working box. But I am sure that somehow DHCP answers tried 
to be send to a non existing interface.
When I discovered the missing bridge interface and added manually by 
brctl and vconfig problem is solved.
Evidence of problem can be found by greping ifname's in nvram and 
comparing existing interfaces. I think each ifname must exist as a 
network interface.
