[Soekris] net4501 woes

[Heather Lockridge]

Hi all, 

An odd thing is happening.

I have been working with net 4801s as my earlier post about modems shows.  I was handed a net4501 by my boss yesterday and asked to build a linux system on it.  With the 4801s I boot from an nfs root partition and then copy it to a CF card. I learned this from posts in the list.

So, I built a 2.6.20.4 kernel like I have been using recently on my net4801s. I changed the processor subarchitecture type to Elan and updated my tftp server parameters so that the new kernel would be loaded by PXEboot.

When I boot the net4501 with 1.31 Combios, the new kernel is loaded and then stops after this:

IP-Config: Complete:
      device=eth0, addr=192.168.1.228, mask=255.255.255.0, gw=192.168.1.2,
     host=192.168.1.228, domain=localdomain, nis-domain=(none),
     bootserver=192.168.1.121, rootserver=192.168.1.121, rootpath=
Looking up port of RPC 100003/2 on 192.168.1.121
Looking up port of RPC 100005/1 on 192.168.1.121
VFS: Mounted root (nfs filesystem).
Freeing unused kernel memory: 188k freed

In other words, the kernel on boot seems not to be picking up the rootpath from the pxeboot default file, which contains:

DEFAULT soekris
SERIAL 0 9600
label soekris
  kernel  vmlinuz.net4501
append console=ttyS0,9600n81  root=/dev/nfs nfsroot=192.168.1.121:/soekrs-root ip=dhcp panic=10 ramdisk_size=16384 rw

The only change in this file from the one used for 4801s is the kernel name.

On the 4801s which boot fine this way, the corresponding set of boot messages are:

IP-Config: Complete:
      device=eth0, addr=192.168.1.226, mask=255.255.255.0, gw=192.168.1.2,
     host=192.168.1.226, domain=localdomain, nis-domain=(none),
     bootserver=192.168.1.121, rootserver=192.168.1.121, rootpath=soekris-root
Looking up port of RPC 100003/2 on 192.168.1.121
Looking up port of RPC 100005/1 on 192.168.1.121
VFS: Mounted root (nfs filesystem).
Freeing unused kernel memory: 172k freed
INIT: version 2.85 booting

and then it boots off the nfs served root partition.

I know this is an odd question, but does anyone have an idea why the "root-path" is missing on the 4501?

Thanks,  I appreciate the help of this list.

Regards,

Heather
