doh, I missed that.
It's presumably not the driver and nobody else seems to be hitting
this, so
it must be something peculiar to your setup. But I don't know what it
might be, sorry.
Actually it has been reported by several other people here including
myself but it seems to have been overlooked here ;)
See the messages with forcedeth in the subject line over the past few
weeks.
I put 2.6.20-gentoo on my machine this weekend with debug printks
enabled and right now I have yet to lose connectivity -- going on ~20
hours worth.
Previously I would lose connectivity within minutes of booting up. I
had a script set up that detected the ping loss of a gateway and would
restart both interfaces (dual onboard nics).
Tonight I will disable the debug printks and see if the system remains
online. There was a big patch applied to forcedeth for 2.6.20,
previously I was having these issues for several of the -19 series.

For all those who are having issues, please try out the attached patch.
