Re: Custom Kernel Networking support

Hello All,

I was experimenting with creating a custom kernel. The only thing I changed from the config that was currently running on the machine was the Timer Frequency was changed from 250Hz to 1000Hz, but it has somehow knocked out the networking where I see the following in dmesg:

root@v100:/usr/src/linux-2.6-2.6.32# dmesg | egrep -i 'eth|bond'

The following steps were taken:

# cp -p /boot/config-2.6.32-5-sparc64 .config
# make menuconfig
<Changed the Timer Frequency from 250Hz to 1000Hz>
<Exit><Exit>
# diff .config.old .config

Can anyone see what is making it fail? Note, I have ONLY changed the Timer Frequency and nothing else

Thanks SO much
