Fwd: Lost Network connection after kernel recompile on G4


I found the answer on a Debian-User post as follows:

In addition to the other suggestions you've received, it's possible you didn't include support for DHCP in your kernel. It's in the 'networking
options' section of menuconfig.

This may be misleading to kernel config newbies, since there isn't an option
for supporting DHCP.

The options are CONFIG_PACKET and CONFIG_FILTER, and they are the first and
sixth options in the Network options section of the kernel config.

I hadn't included Socket_Filtering - I did so, recompiled and Hey Presto DHCP works ;-)

Subject: Lost Network connection after kernel recompile on G4


I have a PowerMac G4 (Gigabit ethernet) 450Mhz dual processor. It has been working fine on the LAN using the standard 2.4.18 kernel. Currently I'm still dual booting (MacOSX) using Yaboot 1.3.8.

I recompiled the kernel for SMP support and after a couple of tries the new kernel compiled and installed successfully. However, I seem to have lost network connectivity - I can't ping the Router which is also the DHCP server. I haven't found a way to post the output from dmesg to the Mac side so that I could attach it but I believe the relevant entries are as follows:

eth0 PHY ID 0x00206047

(last four lines of dmesg below)
eth0 Found Broadcom BCM5400 PHY Gigabit
eth0 Link state change, phy_status: 0x616d
eth0     Link up ! BCM54xx aux_stat: 0xf534 (link mode: 5)
eth0     Full Duplex: 1, Speed: 100

The above would suggest that ethernet is working fine. I went back to menuconfig to check that I hadn't missed a vital networking ingredient and compiled again but no improvement resulted.

As I've now recompiled twice, I seem to have lost the original kernel configuration to get back to where I was before - so I'm a bit stuck ;-(

Any suggestions or comments would be appreciated.
