Problem on re0

[Sami Halabi]

Hi,
I have a desktop on which being used as a MPD server.
the server isn't that loaded, and the cpu is highly idel 90-92% of the time.

My problem is in the network card connected to the cables provider.
in a random manner ot stops working whith no notice, and all l2tp/pptp
users disconnect,
also the provider side stops answering my pings until i ifconfig down the
card and ifconfig up it gain.
As a work around i wrote a script that does ping every 2 minutes and if the
ping timesout it do:
ifconfig re0 down
sleep 1
ifconfig re0 up
mail me about it

I had FBSD-8.1-R and upgraded yesterday to FBSD-8.2-p4, and did
freebsd-update fetch/install.
but the problem persists, i got already 4 emails since the upgrade (and
didn't pass yet the 24 hours).

here is the plot of lspci:
01:06.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8169
Gigabit Ethernet (rev 10)
01:07.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8169
Gigabit Ethernet (rev 10)
(the 2nd driver isn't used, and no cable connected).
