After updating the kernel to 3.17 I no longer have any network interface. I have a Realtek device and use the r8169 driver. According to lspci the device is dected by the driver:

but ifconfig shows only the lo interface. Perhaps there's some new setting that I need to enable?
Here's my kernel config: http://pastebin.com/Cc5PAuZA

I booted the old 3.16 kernel and I still didn't have the interface. Now I don't know what to think. I know the device works since I doual-boot with Windows.
The thing worked on 3.16 without a hitch, then I installed 3.17, rebooted and it stopped working. Now it doesn't even work on 3.16. I feel like I'm either stupid or going crazy.
Ant P.: where do I find this utility? I don't have it installed. |

The box I'm using now has a Realtek r8169 and was installed with and is currently running 3.16.3, using the in-kernel drivers.
I've got the source for 3.17.0 loaded, but haven't built it yet.
I think I'll wait just a bit.

Ok, I figured it out, it was caused by updating networkmanager from 0.9.10.0 to 0.9.10.0-r1 (which I updated at the same time as the kernel). It crashes with
| Code: |
Oct 15 07:10:47 localhost NetworkManager[24686]: <error> [1413349847.969161] [main.c:613] main(): failed to initialize settings storage: Could not load plugin 'ifnet': /usr/lib64/NetworkManager/libnm-settings-plugin-ifnet.so: nie można otworzyć pliku obiektu dzielonego: Nie ma takiego pliku ani katalogu
|
(it says "no such file or directory")
I assumed it was a kernel problem because I thought a network interface would always show up in ifconfig. Apparently this is not true. (it did show up in ifconfig -a). |
