DHCP problem w/ onboard NIC?

Hi,

I just installed suse v9.2 on an AMD64 system using the ABIT AV8 mobo
with onboard Gigabit NIC. This is kernel 2.6.x.

Everything seemed to install fine; however, every 30 minutes or so
my network drops out and I have to do /etc/init.d/network restart
to get it back up.
As far as I can tell my DHCP settings (using Lynksys router) are
the same as my old Suse 8.2 system which had a separate NIC.

Does anyone know what's going on? Googling around a bit, I've read
that some folks don't like the onboard Gigabit NIC; anyone know
anything about this?

All help appreciated,
Peter

This is, to be more specific, kernel 2.6.8.

What's the actual status when the network "drops out"? Have
you lost the ip address (ifconfig), have you lost the card
(ifconfig -a), or have you lost link beat (/var/log/messages
should be informational in that case)?

I take for granted that you've run online update to get the most
recent kernel for SuSE 9.2 in? It may still be 2.6.8, but a lot
of drivers have been patched and upgraded in the more recent
ones.

Yes, that's correct. In fact 2.6.8.24.11 (inc. all Suse 9.2 kernel updates).

The network just seems to be very unreliable; playing with it a bit more,
it now seems that I can wait for a few minutes and it 'comes back' by
itself (without the network restart). I'm pasting in the results of
ifconfig and ifconfig -a below. The output appears to be much the same
before, during and after one of these down periods. I am getting some
odd stuff in my /var/log/messages file however and I'm not
experienced enough to know what it means. That's also pasted in right
below.

Thanks for looking at this for me.

Regards,
Peter
