Rich: can you post the contents of your /etc/modules.conf file?

The /etc/modules.conf is attached. The changes from the (original?) Nov 11
version are adding the "alias usb-controller usb-ohci" line and the "options
natsemi irq=11" lines, plus the comment line re changes must be made to
modprobe.conf. In modprobe.conf, the only change wrt eth0 or the natsemi was to
move the "alias eth0 natsemi" from the first line under the opening comment to
the last line in the file.
All appears well now with the 2.6.10-1.760_FC3 kernel: normal startup,
a happy network. Thanks!
This sounds very similar to the problem I'm having. I installed... FC4 was
looking nice... Added my normal programs such as ICAclient and updated firefox
with some plugins. I decided to reboot and BOOM! When the system came up it
couldn't find the eth0 module. I inserterd the module manually from
/lib/modules/* (modprobe eth0 doesn't work at this point). Started the network
and continued to configure my system and found that there were many modules
missing. The drivers for my usb mouse were present in /lib/modules* but were
not loaded by the kernel. Also, file system modules such as smbfs and cifs were
not loaded. There are others!!! I believe this is a problem witht he kernel
for fc4. I'll create a bug report for this issue. FYI: This also happened with
the enterprise edition aka RHES 4
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem. Please update to this new kernel, and
report whether or not it fixes your problem.
If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.
Interface eth0 starts correctly and successfully binds module natsemi.ko, in
released kernel versions except for release 2.6.10-1.741_FC3.
Works fine in kernel-2.6.12-1.1372_FC3. Status changed to resolved: WORKSFORME.
