Networking issues with 2.6.27 build

[anup_sankaran]

Hi,


Iam trying to compile and install the lnyx 2.6.27 kernel version. In this process i used the .config file of (SLES 10) kernel 2.6.16. on x86_64 architecture.

I could get the kernel boot the system sucessfully, with the perhiperal devices like the keyboard, mouse are working fine.

However iam facing issues in bringing up the network. Even the loopback interface does not seem to come up. I cannot ping to 127.0.0.1, the error message is "interface not available".

The card which i have is

Ethernet controller: Broadcom Corporation NetLink BCM5785 Gigabit Ethernet (rev 01)
and the lspci -vvv shows the driver module as "tg3".

I have configured the same in my kernel build to use tg3.



The dmesg - output is this, and the lspci -vvv is as below. Could you pl help me in this process, since iam doing this for the first time and put all efforts to come so far.

Thanks,
Anup

Any inputs pl..

I would have been very surprised if that .config file worked for you, since there are a lot of differences between how you need to configure your kernel for lynx and sles. You need to configure it yourself, either with the command "make menuconfig" or "make xconfig". The first one will bring up a curses-based text menu, and the second will bring up an X11 GUI window, assuming you are running under a GUI window manager such as KDE, Gnome, XFCE, etc.

Thanks for the reply.
Basically i did a make oldconfig and then did a make menuconfig where i selected the processor model, usb modules, file system, and this Tigon3 driver.

So do u mean that i should not be using the .config, of this system installed with sles os??

Well, if you did that, and you saved your work, you re-created .config with the new settings, so in effect you undid whatever was in the old .config file. At this point, I don't have enough information to help you sort this out. Since it seems your network is not coming up properly, then I think you have not configured that properly. I reconfigure and rebuild kernels all the time, for a variety of different distributions (RHEL, Ubuntu, Debian, Gentoo) and this is not a problem for me. I know EXACTLY what network stuff I need to enable in the kernel. If you are not sure, then use the defaults. You may get more stuff than you want, but you will likely get what you need...
