Hi,
I have just upgraded from Fedora Core 3 to Core 4.
My ADSL internet connection under Core 3 using a speedtouch modem
and the built in kernel support worked fine before the upgrade.
There seems to be some conflict between pppd and the kernel
but as I don't understand the messages I'm guessing.
The kernel is 2.6.11-1.1369_FC4.

I get the following messages in the logs

If anyone needs anymore info please let me know and I'll supply it.

I hope someone can give me some pointers.
Thanks.

Hi,
Just answering my own post.
Problem solved.
SELINUX was protecting the PPPD daemon, so I have disabled SELINUX.
Everything works now as before.
Just thought I'd let people know.

Bye and thanks for reading my post.
