John,
I think you have two issues here: which kernel to
use, and whether it supports the Realtek ethernet NIC.
First, are your nodes uni or SMP? OSCAR by default
will install an SMP kernel, which is usually benign on
a uni, but sometimes causes crashes. So, if your nodes
are unis, then I would install the uni kernel first.
Jason gives the URL in another post to this mailing
list on how to do that.
Now, the other question is whether Realtek support is
turned on for the kernel you decide to use. I just
looked at a 'stock' kernel from Mandrake 8.2, the one
distributed with the distro, and in that one Realtek
support is modular,and it does turn on support for
older Realtek NICs. So, you need to take a look at
the .config file for the kernel you decide to install
and see if Realtek is turned on.
It sure sounds like from your description that
Realtek is turned on for the network boot kernel (used
during installation) and then not turned on in the
kernel that you install on the nodes (or modular
support was turned off in the kernel, which is really
unlikely)... hope this helps, Rich
