Bug Description

Binary package hint: linux-image-2.6.15-22-k7

I have a box which uses a nForce2 ethernet controller:

0000:00:04.0 Ethernet controller: nVidia Corporation nForce2 Ethernet Controller (rev a1)
        Subsystem: Asustek Computer, Inc. A7N8X Mainboard onboard nForce2 Ethernet
        Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 22
        Memory at e9000000 (32-bit, non-prefetchable) [size=4K]
        I/O ports at e000 [size=8]
        Capabilities: <available only to root>

It boots up fine using 2.6.12-10 on breezy, but after upgrading to 2.6.15-21 it will no longer detect the device.

It's on a diskless/nfsroot setup, the initrd image is transfered over the wire, but the kernel fails to find the device so the nfs root cannot be mounted.

Can you boot with "break=premount" and when it dumps you to a shell, try "modprobe forcedeth" to see if it loads manually?

kernel first says:

after loading the module manually I get this:

And on Breezy, it works fine (though there's an odd warning in the dmesg, no issues in practice occur):

In breezy, the driver just ignored the missing PHY. Made dapper do the same.

You need to upgrade to latest version. Verion 0.29 is really old. The latest version is 0.56.

There has even been a fix for phy addresses.

Why are you patching a really old version? I am assuming that ignoring that message will still allow networking to work (even though you never initialized the phy)?

Networking does work indeed even without initializing the PHY. I believe the reason Ben patched the version is that we were already very close to Dapper freeze. The edgy kernel will most likely include the new version.
