e100 module problem

Message

sardiskan · Post by **sardiskan** » Mon Dec 20, 2004 3:00 pm

I get the following error on boot:

missing kernel or user mode driver e100
... can't load module e100

I don't know if that affects me because my network is working just fine and I don't see any problems as of right now. I would like to get rid of the problem though. I've been trying to read the forum and nothing I have read helps. The forum talks about compiling the module into the kernel, I don't know how to do that. Nor do I know if it is neccesary in my situation. I don't know how to check to see if it is compiled in it or not. I would appreciate any help.

First off at what point is it saying this ? is it saying it when it is loading the modules from your
/etc/modules.autoload.d/kernel-2.6 ?

Because if it is just open up that file and comment out the line that says "e100"

FYI about the kernel:
Also as far as the kernel goes i assume you know how to compile the kernel, (if not let me know)
Once open the driver you are looking for is:
Device Drivers -> Network support -> Ethernet (10 or 100Mbit) -> Intel(r) PRO/100+ support
Not that if you open with xconfig, if it has a tick in the tick box it is compiled into the kernel, if it has a dot, it is compiled as a module.
Not that if you open with menuconfig, if it has a * in the box it is compiled into the kernel, if it has a "M", it is compiled as a module.

note: a e100 driver made by intel can also be installed via portage, however i would stick to the kernel version your life will be that much easier.

If your networking is working properly, I'd say that somewhere you're trying to load a driver that you don't need or have installed.

At the command line, as the root user, do the following (will search for references to that driver):

Code: Select all

cd /etc
grep -R e100 .

Don't forget the period. That should (hopefully) spew off some findings... If it does find something, one of them may look like this:

Code: Select all

./modules.autoload.d/kernel-2.6:e100

or something to that effect. If so, you can continue.

The modules.autoload.d directory contains a simple text file for each major kernel you have installed (2.4 and 2.6, if you have a 2.6 kernel installed... odds are, if you haven't installed a kernel before, you will only have a file called kernel-2.4.

If you edit the kernel-2.4 (or kernel-2.6) file that the 'grep' called returned and remove the e100 line from it, you shouldn't have the warning anymore. Basically, listing a module name in that file will cause Gentoo to automatically try to load the module into the kernel - commonly used for networking and video cards.

Hopefully that helps.

Damn, I got beat to the punch by another poster!

No I don't know how to compile the kernel, I used genkernel to compile it so I'm not educated about the manual compilation.

Also, when I run the grep -R e100 .
I get no findings. What does that mean?

Jason

can you post the output of theses two commands please

Code: Select all

cat /etc/modules.autoload.d/kernel-2.4

and

Code: Select all

cat /etc/modules.autoload.d/kernel-2.6

(you can ignore all like that start with a "#" symbol)

Ok I know nothing about genkernel, i think it is the devil doings, so you may have to read the man page on that.

to compile a kernel manually, i would suggest reading the gentoo handbook as that will give the instructions better than i can, if you don't understand it post back here what you don't get and i will try and explain it.

The first command has this output

Code: Select all

# /etc/modules.autoload.d/kernel-2.4:  kernel modules to load when system boots.
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/modules.autoload.d/kernel-2.4,v 1.1 2003/03/09 09:06:23 azarah Exp $
#

The second command has this output:

Code: Select all

# /etc/modules.autoload.d/kernel-2.6:  kernel modules to load when system boots.
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/modules.autoload.d/kernel-2.6,v 1.1 2003/07/16 18:13:45 azarah Exp $

It actually looks like every line is commented out. Let me know what else you need.

Ok then that means it is not being loaded by the /etc/modules.autoload.d/kernel* files.

What kernel version are you useing ?
What is your network card ?

what is the output of

Code: Select all

emerge -vp e100

Can you say where in the boot up process the error is comming up ?

sardiskan · Post by **sardiskan** » Mon Dec 20, 2004 5:18 pm

The output of the command you gave is:

Code: Select all

router root # emerge -vp e100

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild   R   ] net-misc/e100-2.3.40  0 kB

Total size of downloads: 0 kB

I am running kernel version 2.4.26 and my network card is an Intel S82557 PCI card. The error comes up towards the end of the bootup right after is says "coldplugging pci devices" but before "coldplugging pnp devices"

I got this error when I used Genkernel.
Are you using genkernel? Maybe you should try compiling your own...

try,

Code: Select all

emerge --unmerge e100

(if after you reboot, you don't have any network access then you will have to remerge it with command "emerge e100")

sardiskan · Post by **sardiskan** » Tue Dec 21, 2004 1:00 am

I actually emerged it AFTER I was getting the error in hopes that it would solve the problem. I'll unmerge it, but I"ll still have network access but the message will not go away.

I suspect this is a genkernel thing, so i were you i would compile my own, as aragostaragazzo suggested.

sardiskan · Post by **sardiskan** » Tue Dec 21, 2004 4:52 pm

Ok, I'll try and compile my own.

Don't fear, it's really not that difficult.

You could always ignore the problem if its not causing any problems

Yeah, but, when youre booting up Linux to impress all your friends, you can't have error messages flood the pretty boot-process...
