Hi,
When trying to build on v6.5-rc4 with python 3.12 aka Python 3.12.0rc1 I am
hitting the below Warning messages.
I didn't see something similar reported upstream, hence thought of reporting.

However I am not seeing this when using python 3.10 (Python 3.10.12) and
python 3.11 (Python 3.11.4). Note this is just a warning and Kernel build does
complete.
