Hello there.
Although the kern/67636 PR was closed before FreeBSD 5.3-RELEASE,
I'm experiencing exactly the same problem on my FreeBSD 5.3-RELEASE-p5:
saturn# ls -al /boot/kernel/ipl.ko
-r-xr-xr-x 1 root wheel 92883 Jan 17 12:18 /boot/kernel/ipl.ko
saturn# kldload -v /boot/kernel/ipl.ko
kldload: can't load /boot/kernel/ipl.ko: No such file or directory
saturn# dmesg | tail -1
link_elf: symbol in6_cksum undefined
And following is the contents of my kernel build configuration file.
As you can see I've disabled INET6 but enabled IPFIREWALL and IPDIVERT
for some other use. Before trying ipl I was using ipfw with natd.
