Recent LTS kernels break PPS

I am using a AML-S905X-CC with Debian 12 as a local time and DNS server. I use LTS kernels and noticed that PPS stopped working with 6.12.71-g1688fd943ab9 and 6.12.73-g6b2d05eda916. I have not tried 6.12.74-g8d0dd6a4613b. I have no issues using 6.12.68-g33f31827bcf4. Is there anything I can provide to assist with troubleshooting and fixing this issue?

We will test this tomorrow and let you know.

I appreciate any assistance and am happy to provide any details needed in case you are unable to recreate this issue.
