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!

I am wondering if the two kernels have different management of iptables,
in particular IPv4 or IPv6, another shot in the dark, even if is
afternoon here
tnx
Antonio,
service iptables stop. I suspect that the IRQ for eth0 is not getting
properly registered and thus the timeouts.
Does specifying acpi=ht on the SMP kernel command line make any
difference? It probably defeats the purpose of SMP.
Bob...
and furthermore prevents from poweroff .... :-(
