    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.
