Fedora 10 and pppoe trouble

[Pasha R]

I installed Fedora 10 few days ago, and since then I have trouble
connecting to internet. I use ADSL (I have ethernet modem, so I have
no driver problems) and it requires pppoe dialing. So, I defined  xDSL
connection with all settings that always worked with Fedora 8 and
previous versions. But when I try to connect, all I get is timeout.
Sometimes it connects successfully and then internet works great.

In message log I see
