 Posted: Sun Mar 12, 2006 6:36 pm Post subject: No eth0 after kernel compilation |
 |
|
Hello!
Several days ago I have installed gentoo, but internet didn't work. I ran ifconfig -a and noticed, that eth0 wasn't listed at all. So I run modprobe 8139too (added to/etc/modules.autoload.d/kernel-2.6) and internet started work.
Today I decided to compile new kernel, because where was no sound with old one. I compiled it ( used http://gentoo-wiki.com/HOWTO_Compile_a_Kernel_Manually ), but it didn't work - "Unable to mount root fs on..." But now, then I try to boot with old kernel, but I get error:
| Quote: | | "* Error loading 8139too" |
later:
| Quote: |
* Starting eth0
* bringing up eth0
* dhcp
* eth0 does not exist [!!]
* ERROR: Problem starting needed services.
* "netmount" was not started |
My ethernet modules were 8139cp and 8139too, but now, when I run lsmod they aren't listed (mii isn't listed too).
So, can anybody help me?
Thanks for answers and sorry for mistakes  |

| Have you added them to /etc/modules.autoload/kernel-2.6? |

If you are compiling a kernel from existing sources, are you certain you rebuilt drivers for your ethernet card(s) ?

| Code: | | emerge -u gentoo-sources |
| Code: | | USE="symlink x86 3dnow 3dnowex X aac aalib adns alsa apache2" |
| Code: | | make && make modules_install |
| Code: | | cp arch/i386/boot/bzImage /boot/bzImage-new-kernel |
That's all I did. |

Did you confirm that you built drivers for your nic, either compiled in the kernel, or as modules?
| Code: | Device Drivers --->
Network device support --->
Ethernet (10 or 100Mbit) --->
[*] Ethernet (10 or 100Mbit)
<M> Generic Media Independent Interface device support
<M> RealTek RTL-8129/8130/8139 PCI Fast Ethernet Adapter support |

Really I even didn't look at NIC driver. I have compiled kernel for Slackware and I never had such a problem.
Could you tell me, what are the differences between a driver compiled as module and compiled in kernel? |

Compiled-in is static, is a driver I would say. You can't load/unload it.
Modules can be dynamically loaded/unloaded.
Some people used to say that if you don't chande your hardware often you can have all needed things compiled-in as drivers.
Just find your way:) |

Thanks, kfiaciarka.
And another question: I always configure kernel with make xconfig. And I can mark driver with tick and circle. Can anybody tell me, what do they (tick and circle) mean? |

tick = compiled into the kernel..
dot / circle = compiled as a kernel module..

Yesterday, after I tryed to compile new kernel I got error:
| Code: | # modprobe 8193too
FATAL: Module 8193too not found
# modprobe 8193cp
FATAL: Module 8193cp not found |
Today I compiled my NIC drivers as modules. But they still not work. I get:
| Code: | # modprobe 8139cp
FATAL: Error inserting 8139cp (/lib/modules/2.6.15-gentoo-r5/kernel/drivers/net/8139cp.ko): Invalid module format
# modprobe 8139too
FATAL: Error inserting 8139too (/lib/modules/2.6.15-gentoo-r5/kernel/drivers/net/8139too.ko): Invalid module format

You did compile in support for Loadable modules, right ?
| Code: | Loadable module support --->
[*] Enable loadable module support
[*] Module unloading
...
[*] Automatic kernel module loading |

Yes, I compiled it in kernel.
Perhaps 8139cp and 8139too don't work, because of mii module? Kernel doesn't load it automatically and when I run modprobe mii, I get:
| Code: | # modprobe 8193cp
FATAL: Module 8193cp not found |

Can you supply the outputs from:
| Code: | # ls -l /lib/modules/`uname -r`/kernel/drivers/net
# lspci |

I'm having the exact same problem, although I'm using the a 3com card (3c59x module, which always worked before)
First I did genkernel all, then everything worked, but my i had some clock problems so i should build the kernel manually. From then on, i always get invalid module support (even if i load the old genkernel) |
