Ifconfig(s):
Seems that the non-SMP kernel works fine.
Here is the ifconfig;
[root@localhost root]# uname -r
2.6.6-1.435.2.3
[root@localhost root]# ifconfig

[root@localhost root]#
But the SMP kernel has issues;
[root@localhost root]# uname -r
2.6.6-1.435.2.3smp
[root@localhost root]# ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0

[root@localhost root]#
Then I did the static IP number thing, but had/have a communication problem;
[root@localhost root]# ifconfig eth0 down
[root@localhost root]# ifconfig eth0 192.168.0.49 netmask 255.255.255.0 broadcast 192.168.0.255
[root@localhost root]# ifconfig eth0 up
[root@localhost root]# ifconfig

Not to switch gears on you, but...
I have a "fix", through some feedback from the fedora-legacy-project list I was directed to send the command 'noapic' at boot time. To see if this would have some effect on the IPv4 problem.
This allowed IPv4 to operate with the SMP kernel!!!
So, can anyone explane what is going on with this...
Is it my motherboard/bios having communication issues with the SMP kernel, but not with the non-SMP kernel?
Thanks, Denis, for you assistance with this issue.
