i have a very similar problem (i think) , but with the 2.6.24-19-generic
kernel :
After a while (can be very long, or just 5min ...) , ehternet connexion crash,
adn I get this message in dmsg :
[ 2334.384327] NETDEV WATCHDOG: eth0: transmit timed out
[ 2335.212774] r8169: eth0: link up
When it happens, the only way to make it work again is to restart the
computer.
/etc/init.d/networking restart do nothing
If I unload/reload the r8169 module, the mac in ifconfig become
ff:ff:ff:ff:ff:ff
I noticed that it happen smore often when Azureus is running ..
Moreover, I do not know if it is the same bug, but if I plug the
ethernet cable when the system is booting, most of the time my ethernet
connexion will not work at all. I need to plug it before turning on the
computer of after beeing logged-in to be sure it will work (at least at
the beginning..)
I can not test Intrepid Alpha right now, I will be able in 2 weeks i
think.
Here is my lscpi -v :
