To help ensure the quality of the Linux Kernel I'm using the git-sources package.
Up until now I never experienced any trouble with an experimental kernel. But with 3.8 something strange is happening to me.
I thought I'd bring it up here first to make sure it wasn't a configuration error or anything.

So here's the problem:
When I boot up my machine (a Lenovo x230 notebook) with Linux 3.8(-rc[123]) my ethernet is not working. The driver is loaded. ifconfig lists the interface. But it is not seen by ethtool or mii-tool.
Code:

lale1202 ~ # mii-tool eth0
SIOCGMIIPHY on 'eth0' failed: No such device
lale1202 ~ # ethtool eth0
Settings for eth0:
Cannot get device settings: No such device
Cannot get wake-on-lan settings: No such device
Cannot get message level: No such device
Cannot get link status: No such device
No data available

After sending the notebook to Standby (ACPI S3) and waking it up again however, the ethernet works just fine!

I don't know why this is. The config for the kernel was generated with make oldconfig from the 3.7.1 Kernel which is working just fine. I also had a look at the config and didn't find anything. It should be fine. You can find my Kernel config here: http://pastebin.com/fW7baaUd

Here's the ethernet specific output of lspci -v
Code:

00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (rev 04)
        Subsystem: Lenovo Device 21f3
        Flags: bus master, fast devsel, latency 0, IRQ 44
        Memory at f1500000 (32-bit, non-prefetchable) [size=128K]
        Memory at f153b000 (32-bit, non-prefetchable) [size=4K]
        I/O ports at 4080 [size=32]
        Capabilities: [c8] Power Management version 2
        Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+
        Capabilities: [e0] PCI Advanced Features
        Kernel driver in use: e1000e
        Kernel modules: e1000e


So I can't figure out what it is and I'm wondering if it is an actual regression? And how would I report that to the Kernel maintainers if it was (because that's kind of the point of using the rcs).[/code]
