Hi Bagas,

I seem to have run into a dead end with this.

OpenSSL 3.0.2 refuses to cooperate, despite enabling legacy ciphers:

   BTF [M] net/nsh/nsh.ko

make -f ./Makefile ARCH=x86     KERNELRELEASE=6.3.0+ intdeb-pkg

I have tried to enable NEXT crypto mode:

% sudo update-crypto-policies --set NEXT

and rebooted, but no use.

Google also doesn't give a clue.
I have been able to compile kernels on Ubuntu 22.04 LTS on my laptop 
just about a year ago.

Thank you.
