I just went back and tried kernel-2.6.13-1.1526_FC4 and the network is broken there too...

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.

I've had the same sort of issues with an RT2500 card; need to compile the module for each new kernel I use, and starting the ntpd service during boot usually causes a hang. Is there a special kernel module needed for your NC100 card? You might need to compile and install it for the new kernel, I don't know about that particular card. You could also try turning off the ntpd service at startup, and start it manually after bootup and login, that is what I do...

I've never needed to compile a kernel module for this card. It's always worked (right of of the box). When I look at the pull down list of supported network cards, it's in the list.


Ok, next question is, is the module loaded?
# lsmod | grep <module_name_of_card>

I don't see anything regarding "linksys" or "nc100", but I *do* see the "tulip" module. (This is from the kernel that works.)

I'm not at the location of the machine, so I can't try re-booting and checking under the new kernel.
