so the problem is ipv6 module is still being loaded, something explicitly might be loading the module. You could take a shotgun to it and delete the module from /lib/modules/$(uname -r)/kernel/net/ipv6/ipv6.ko

I would try and find out what is loading ipv6.

first I would boot with the option init=/bin/bash, check lsmod, this will tell you if it is the initrd. Then just start each of the daemons in the same order that init would.

Sorry can't point to the exact answer, but you should have the tools to track it down.

(one other place to check is /etc/sysctl.conf)

Good luck
