No network connection after upgrade (via 'yum')

[Jon D. Slater]

Hi All,

I just recently did a 'yum' update to my existing FC4 install, and 
re-booted.  The 'yum update' updated my kernel.
kernel-2.6.12-1.1456_FC4    -->   kernel-2.6.13-1.1532_FC4

My network connection stopped.

If I look at the network support tools, it looks like everything is working.

During boot, I see the network service start (appears fine), and the a 
long pause when trying to connect to the nntp "Time Server" (which Fails).

If I reboot using the old (2.6.12-1.1456) kernel, everything works fine.

Typically when I've yum-updated before, everything that's needed to 
support the kernel "comes with it".

I'm running FC4 on an HP Pavilion 8150, with a Linksys NC100 (Network 
Everywhere Fast Ethernet 10/100 [rev 11]) card.  And I've never had any 
problems, until now.

Obviously, this isn't an urgent issue, because I can boot using the old 
kernel, but does anyone know of something I should have done?

My first thought when this happened was that my network card had died, 
so I replaced it with a 3 Com 3c905, and got exactly the same problem.  
(That's when I tried putting the old card back in and booting using the 
old kernel.)

Any suggestions would be GREATLY appreciated.

Jon
