Just an update.

Binary search of patches didn't work because when I build the
kernel with my build script the problem doesn't occur, but I
confirmed that with the kernels in the snapshots it does.

I am now doing an rpmbuild to see if that kernel works and
to get a trace to see what the differences are in the build
Comment 3 George Beshers 2007-09-06 18:40:19 EDT
Sigh... Nothing to do with the kernel.  The problem is that
in snap3 and snap4 /etc/sysconf/network does not get a
GATEWAY entry.

Not sure if this is related to the number of devices or if
there is something else going on.

The system where the problems occur has 8 ports with 6 active
and 4 connected all to the same subnet:

         inet addr:  Bcast:  Mask:
          inet addr:  Bcast:  Mask:
          inet addr:  Bcast:  Mask:
          inet addr:  Bcast:  Mask:
          inet addr:  Mask:

The following is probably a decent clue, note that /mnt/sda10 is the
root of the snap2 install:

[root@billberry1 ~]# diff -r -q /etc/sysconfig/ /mnt/sda10/etc/sysconfig/
Only in /etc/sysconfig/: dhcpd
Only in /etc/sysconfig/: dhcrelay
Only in /mnt/sda10/etc/sysconfig/networking/devices: ifcfg-eth0
Only in /mnt/sda10/etc/sysconfig/networking/profiles/default: hosts
Only in /mnt/sda10/etc/sysconfig/networking/profiles/default: ifcfg-eth0

Pretty sure notting takes care of all initscripts related stuff.
Comment 5 Bill Nottingham 2007-09-10 16:39:48 EDT
anaconda writes /etc/sysconfig/network.
