Let me try to understand this correctly?
You're building the kernel with
make -j6
but in htop you're seeing a single core at 100% and the rest are idle? Yes, no?
What exact steps are you doing to build the kernel? Type them here please so that I can do them exactly on my system too.
Also, please send a full dmesg from your system, private message is fine too.
Thanks.
