It appears that the KLD build process is missing a ctfmerge at the end, and this results in KLDs with incomplete CTF information.
Here is a patch that fixes this. I verified it on amd64 with various KLDs. Before: # ctfdump /boot/kernel/if_cxgb.ko | wc -l 2269 # ctfdump /boot/kernel/zfs.ko | wc -l 430 After: # ctfdump /boot/kernel/if_cxgb.ko | wc -l 6568 # ctfdump /boot/kernel/zfs.ko | wc -l 15032 It is wasteful to have CTF information in both the .ko and the .ko.symbols file but this is what the kernel does too.
