The context is that I am in the process of bringing up a 2.4.24 kernel (pulled from linux-mips CVS using the linux_2_4_24 tag) on a DBAu1500 board (Zinfandel).

I'm having trouble mounting my root filesystem over NFS. After the ethernet ports have been enumerated, the kernel attempts to contact the DHCP server to obtain its IP configuration information. At this point the boot sequence hangs, perpetually retrying the DHCP server. Here are the last several lines from the log of the boot messages, prefixed with a vertical bar to set them apart:

| Sending DHCP requests .<6>eth0: link up
| eth0: going to full duplex
| ..... timed out!
| IP-Config: Retrying forever (NFS root)...
| Sending DHCP requests ...... timed out!
| IP-Config: Retrying forever (NFS root)...
| Sending DHCP requests ..

I've verified that the exported root filesystem can be mounted by another Linux workstation. I've also verified on the DHCP server that it is seeing the board initiate a DHCP discovery and that the DHCP server is replying with offer for the correct address. Here is an excerpt from '/var/log/messages' on the DHCP server:

| Feb  9 13:25:33 kapala dhcpd: DHCPDISCOVER from 00:50:c2:0c:38:8a via eth0
| Feb 9 13:25:33 kapala dhcpd: DHCPOFFER on 172.16.108.42 to 00:50:c2:0c:38:8a via eth0

For completeness sake, I've attached the full log of the boot sequence until it hangs as well as my current kernel configuration. If any of you have seen this particular problem and know how to get around it, please respond. Further, if you simply have suggestions for avenues I could explore, I would appreciate any advice you might have to offer.


Humbly yours,
