No,
There is no real difference between running a standard kernel or an
SMP one. Bar the fact that SMP will actually use the two processors
in your machine that is. I run SMP myself, and it makes no
difference to my connection running standard or SMP kernel.
I'd look at doing some other diagnostic work before filing a report.
We can't help you for the rest because you don't explain your set up.

My setup is very standard, a Pentium 4 Asus motherboard P5P800, 1 GB,
two network cards (the integrated is connected to my network, the
Realtek 8029 to my ethernet modem).
Which diagnostic shall I check??
upgraded to FC4, same behaviour also with 2.6.12-1.447smp
where to look???
Number one would be to see if the Realtek interface actually comes up -
then there's a whole slew of tools like ifconfig, ping, iptraf, dhclient
etc. to be used one by one to see where the problem lies.
When I asked you to provide more details, I wasn't really after
motherboard and stuff like that, I was after your internet connection
details of course. This is how I would describe one for example:
Maestro Woomera Serial modem connected to /dev/ttyS0
Using pppd on demand/wvdial to make a connection
The IP address on that interface (ppp0) is assigned dynamically by my isp.
The log shows dialling to be ok, and pppd taking over the connection
once wvdial has established it.
ifconfig shows an IP allocated to me ip address: 203.0.178.191 with
netmask 255.255.255.0.
I can ping internal addresses and external ones by name
(www.microsoft.com) and number (207.46.199.60).
This is in the case of dial-up. Your trace will be different.
Really, you have provided nothing of use in diagnosing this problem. I'm
assuming your modem takes care of the connection and just gives you an
internal IP address which you set to the gateway? or do you need to run
PPPoE or some other protocol manually?
You must assume we know nothing about your set-up when posting to this
list.
Regards,
Ed.
Ed,
it seems that I can't ping the Ethernet modem when using SMP
kernel(destination unreachable), if I connet to ist internal webpage I
get a message of no routing.
I have iptables running: and everything is o.k on standard kernel!!!
What is happening???

Anything relevant in /var/log/messages? What is the output of route -n?
Bob...
I had a look at /var/log/messages (that I attach, only as e-mail to
you...), but I am not very expert.
I see a timeout transmit on eth0 repeated many times when using SMP
kernel at about 6.35 at the end.
I see also many errors conencted to ACPI (on both kernels) that I am not
able to decode
Tnx
Antonio,
I culled the messages down into a SMP boot and a UP boot. A quick look
indicates one message is missing in the SMP boot log. It's marked with
an arrow and indicates that the eth0 device interrupt was detected as
IRQ 11 (UP only). Hopefully someone can shed some light on this. Some
other information that might help:
cat /proc/interrupts for both the UP and SMP.
Also, do you have the latest BIOS installed for your motherboard? What
kind of motherboard is this?
An Asus P5P800, Bios updated in July
Check the IO-APIC options in the BIOS
setup.
You might try moving the realtek NIC to another slot. That's a shot in
the dark, but it's pretty early and I'm only into my first cup of
coffee!
Bob...

I am wondering if the two kernels have different management of iptables,

afternoon here
