I just checked and the fix I was referring to earlier didn't make it into 2.6.21-final. You can get 2.6.21-git1 from kernel.org which has the fix. See

Good. So I tried that patch (well, actually only the change visible at
http://lkml.org/lkml/2007/3/6/268). I patched it into a 2.6.20.11 kernel,
using the same config file as previously. The good news is that this fixes
my issue: there are no lost ticks anymore, and the link does negotiate a
gigabit connection. This is a great improvement for me :)

I still seem to hit an issue if using the ethtool command, though.
when using 'ethtool -s eth0 autoneg on', the link comes up at gigabit speed,
but a couple seconds later is comes down again, and then up at 100 megabits:

e1000: eth0: e1000_watchdog: NIC Link is Up 1000 Mbps Full Duplex
e1000: eth0: e1000_watchdog: NIC Link is Down
e1000: eth0: e1000_watchdog: NIC Link is Up 100 Mbps Full Duplex
e1000: eth0: e1000_watchdog: 10/100 speed: disabling TSO

The same thing happens if I use ifdown eth0; ifup eth0 too. Once again,
I only observe this on my DQ965GF motherboard, the DG965RY board is fine
(stays at gigabit speed when I issue these commands).

Is this something you could easily reproduce at Intel or would you want me
to look into that issue on my system ?

I think we have confirmed this issue and I'll work with Bruce on seeing where the fix went. I might give you another patch to try.
