Hi, I am running RH linux 2.4.7-10 kernel on Del Optiplex GX 110 (with 256MB RAM). The system boots fine with networking on. Then I added a virtual network interface to the kernel (similar to the one available at ftp:/ftp.linux.it/pub/People/Rubini/insanetar.gz). (There is no change made to drivers/net/loopback.c). I could build the new kernel wihtout any error. However, when booting with this kernel image, the system hangs at "Bringing up interface lo:" (it does not give prompt "[OK]"). The system however boots fine in single user mode. I ran "/etc/rc.d/init.d/network start" after booting the system in single user mode. I checked that it is getting stuck at "./ifup ifcfg-lo". More precisely, in the ifup script it is halting at "ip addr add ${IPADDR}/${PREFIX} brd ${BROADCAST:-+} dev ${REALDEVICE} ..", called to add adrress for lo. I checked that it is correctly using IPADDR=127.0.0.1. Since I have not made any change to loopback.c, I am confused why the system is hanging at this point. I shall appreciate any pointer/suggestion in this regard.
