I have Thinkpad X200 with Libreboot. I tried Gentoo from live USB and everything was ok. So I installed Gentoo on the hard drive and it can't see any web interface in ifconfig. The kernel is compiled like this http://pastebin.com/HqY4SY0B , below I pasted lspci, dmesg and ifconfig. Web interfaces don't work also with genkernel.
Any ideas?

JaGenau,

You have several issues.

First,
Code:
 disagrees about version of symbol module_layout
suggests that the kernel and its modules were built with different versions of gcc or the modules you are trying to load don't belong to this kernel. dmesg usually displays the two conflicting symbol versions.

Regardless of the cause, the fix is to rebuild and reinstall the kernel starting with the
Code:
make clean
step. This discards existing intermediate files so make has to build everything.
Before you do that read on ...

Your network interfaces are
Code:
00:19.0 Ethernet controller: Intel Corporation 82567LM Gigabit Network Connection (rev 03)
02:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01)


You have both the ath9k and e1000e drivers built into your kernel.
The e1000e appears in dmesg but the the ath9k dose not. Taken together with the symbol version issue, heres what I think happened.

Your system booted but with no wireless interface. You added ath9k and rebuilt the kernel and reinstalled it, then rebooted.
However, you forgot to mount /boot, so the kernel binary was installed to the wrong place.
Thes means you are running the old kernel with the new modules - hence the missing ath9k and the symbol version issue.

To test, boot normally and run
Code:
$ uname -a
Linux NeddySeagoon_Static 4.0.3-gentoo #1 SMP PREEMPT Sun May 17 13:21:36 BST 2015 x86_64 AMD Phenom(tm) II X6 1090T Processor AuthenticAMD GNU/Linux

The Sun May 17 13:21:36 BST 2015 is the build time of the running kernel. Does that look right to you?
The #1 is the build number of the running kernel.

The fix is to mount /boot then repeat the kernel install steps.
