Lost network connection... New message

[Jon D. Slater]

I've been having this problem for some time, but now I've got a new error
message.
 
Here's what I did:
 
Out of sheer frustration, I re-formatted my hard drive and re-installed from
my FC4 install disks.
This gave me kernel-2.6.11-1.1369_FC4 which works fine.
 
After testing my network connection, I typed "yum update"
 
This took about two hours but eventually gave me kernel-2.6.14-1.1656_FC4.
 
Rebooted.
 
No network.
 
But this time as the machine boots, right after starting eth0, I get the
message:
"Disabling IRQ #5"
 
When I check the network status from the network configuration screen, the
screen "claims" that eth0 is active.
 
As soon as I reboot using kernel-2.6.11-1.1369_FC4, the network comes back.
 
Any ideas?
