That's going to be ugly, since I can't reproduce it at will. Maybe if
I netperf it to the other box I can push it over.

OK. will try later when I have more time. For now I switched to the
onboard via rhine controller.

Hmm. Having rebooted they look rather lower. but might be a time thing.

OK, it had gone since reboot, but I rebooted just now .... new info
attached.

OK, is going to be hard to bisect, since the other one was an Ubuntu
kernel, but I guess I can give 2.6.15 virgin a shot, at least.

Nah, I'm pretty conservative with hardware, get enough problems when
it's all running within specs ;-)

Thanks for looking at all this.
