Network Unreachable Woes

I am having a problem that I've seen elsewhere. I boot from the LiveCD and networking works find using a NetGear FA310TX2. DMESG says the Linux Tulip driver is loaded. The device is on IRQ10 with a base address 0xb000.

I finally got a kernel built that would recognize an eth0 device (I had to build them into the kernel, the modules I built would not install with modprobe - an invalid module problem). When I 'ifconfig eth0' the irq is 17 and the base address is something really strange.

I though I could pass an 'ether=10,0xb000,eth0" via grub but that doesn't work. Also trying to pass the irq and io_addr via ifconfig fails.

Any ideas? I do notice that many people have problems with networking after building their own kernels. What is magical about the live CDs that allow networking to come up so well while the built kernels are so tricky...

Thanks,
Craig

can you see which modules the liveCD loads ? lsmod
find those modules in the kernel and compile them.

Eh, I'm having a similar issue but using genkernel. I get Internet access using the LiveCD but not with my linux installation.

I checked the modules loaded from using the livecd compared to the ones that were loaded with my installation and none from the livecd were related to this issue. In fact, nearly all the ones loaded from the livecd were loaded from my hd installation.

I have a machine that uses the Tulip driver. I compile it as a module and it loads fine.

Did you put the module name in your /etc/modules.autoload/kernel-2.x directory?

To my knowledge, most modern eth cards never need you to specify IRQ/IO addresses; that was primarily for legacy ISA cards (ala NE2000)

Is your tulip card by chance the 2nd adapter in the system? I had an issue where the built-in NIC failed and I added a tulip card. I had funk until I disabled the failed internal card in my BIOS.

The magic in the Live CD's, AFAIK, is that almost everything is compiled in or compiled as a module, and it also runs the RedHat "kudzu" hardware detection program. That is something else you can try...

Try booting with the "noacpi" kernel parameter. If ACPI is in your kernel, it causes PCI cards to be initialized differently; "noacpi" disables it.
