[SOLVED] Intel Corporation i211 Gigabit Network - missing

[GodOfBSD]

Hi,

I'm missing enp7s0 under ip link. Only shows lo and sit0.

Really struggling here. I have every Intel option [*] checked under

Device Drivers > Network Device Support > Ethernet Drive Support



Dhcpcd is installed from LIVEcd. Anyone got any ideas?

Find . Iname "igb"
/usr/src/linux*/include/config/IGB
^^^^^^^^^^^^^^^/drivers/net/ethernet/intel/igb


modprobe igb

No go

Please post:

1. The output of

   Code: Select all

   lspci -k -v

2. The output of

   Code: Select all

   dmesg

3. Your kernel config

You may want to use wgetpaste.

Hi Mike!

So, a small issue with posting lengthy logs is... I'm unable to connect to the internet on my PC. I'm currently on a phone which I just rigged a keyboard up to respond to you, haha. Are there any specific highlights of those outputs?


I could take a photo with my phone granted that is ghetto haha

[mike155]

Well, I cannot guess what is wrong on your machine...

The first thing you should do: check whether you really boot from the kernel you compiled. Look at the first line of the output of 'dmesg'. There's the kernel version and the time when the kernel was compiled. Do you boot from the right kernel?

Then look at the output of 'lspci -k -v'. You should see your PCI devices and the kernel drivers in use for those devices. What do you see for you IGB Ethernet adapter? Is there a kernel driver?

Sorry, I booted in to liveCD to wgetpaste those outputs.

Okay, 'lspci -k -v' shows the Ethernet controller:

Code: Select all

But no kernel driver is attached. I would like to see:

Code: Select all

	Kernel driver in use: igb

But it isn't there.

Is this the output of "lspci -k -v" when you boot with your own kernel? Or is it the output when you boot with the Livecd?

[GodOfBSD]

Okay, 'lspci -k -v' shows the Ethernet controller:

Is this the output of "lspci -k -v" when you boot with your own kernel? Or is it the output when you boot with the Livecd?

My own kernel. also thanks for looking in to this, I've been going insane trying to get this rolling.

P.S modprobe igb does not return any error nor does then show up in lsmod

[mike155]

What happens if you boot from the Livecd? Can you use the Ethernet adapter when you boot from the Livecd? Do you see a "kernel driver in use" in the output of 'lscpi -k -v" when you boot from the Livecd?

Here is a dpaste of 'lspci -k -v' from the LiveCD.

Code: Select all

It does appear and I do have a internet connection

lsmod | grep igb returns the following

That's good. So there is a driver that works with your machine

One more question. In post #5 above, you posted the output of 'lspci -k -v' and the output of 'dmesg'. You wrote that the output of 'lspci -k -v' was from your own kernel. But the output of 'dmesg' doesn't seem to be from your own kernel. It starts with:

Code: Select all

[    0.000000] Linux version 5.15.19-gentoo (root@livecd) (gcc (Gentoo 11.2.0 p1) 11.2.0, GNU ld (Gentoo 2.37_p1 p0) 2.37) #3 SMP Sun Feb 6 09:52:10 PST 2022

That is the Livecd kernel, isn't it?

Please post the output of 'dmesg' when you boot from your own kernel.

Yeah that's strange, I just redid dmesg from the machine, no flash drive plugged in, and that top line is still there. Here is the dmesg

[mike155]

Please edit your kernel config and disable ALL Intel Ethernet drivers except "Intel(R) 82575/82576 PCI-Express Gigabit Ethernet support". CONFIG_IGB should be defined in you kernel config. All other Intel Ethernet drivers should be disabled. Compile and install your kernel and reboot.

The first line of 'dmesg' should change. #3 should increase to #4. The end of the line should contain the time when you compiled the kernel. Please double-check that to make sure that you boot the right kernel.

dmesg should also show a message from the IGB Ethernet driver. Something like:

Code: Select all

[    0.933875] igb: Intel(R) Gigabit Ethernet Network Driver
[    0.933877] igb: Copyright (c) 2007-2014 Intel Corporation.

Alright, disabled all Intel except what you mentioned, unfortunately no avail. Here are the new logs

modprobe igb - does not return any errors or actually appear in lsmod

Sorry this is turning out to be such a freakshow haha

The first line from dmesg is still:

This tells us that you don't boot from the kernel you just compiled.

Do you agree?

[mike155]

Please tell us how you compile and install a new kernel.

A common source of problems is that the boot partition is not mounted to /boot when users compile and install their kernels.

My usb isn't even plugged in when I boot so I'm pretty sure, I'll paste a dmesg of the liveCD

http://dpaste.com/2WXJJBY6Z

it's quite different, I don't know why my local machines dmesg shows livecd when im on my machine w/ usb drive unplugged

cd /usr/src/linux

Reboot

/boot is automatically mounted

Looks good... Please show us the output of

df -k /boot

GodOfBSD,

Has your clock stepped backwards?
That really confuses make.

Code: Select all

cd /usr/src/linux

make clean  <---- One time added step

make menuconfig

~adjusts settings~

make && make modules_install

make install

Reboot

Add that

Code: Select all

make clean

to cope with time possibly not being monotonic.

This doesn't look like a boot partition. It's too large! And it's not a partition mounted to /boot - it's your root partition.

This seems to be the kernel you just compiled.

But it doesn't look like your boot partition either. Which boot loader do you use? GRUB? There should be files from GRUB in your boot partition.

It looks like your boot partition isn't mounted.

[NeddySeagoon]

GodOfBSD,

The kernel you are running, with a build time of

Code: Select all

Sun Feb 6 09:52:10 PST 2022

is missing too.
/boot is normally a vtat partition, vfat does not support *NIX permissions.

What you are showing loos like a couple of kernel installs to the /boot directory on the root filesystem.
That's what happens when the boot partition is not mounted there.

Ah thank lord, mounting the boot partition and recompiling and updating grub did the trick. Thank you @mike155 and @NeddySeagoon !!!!
