Thanks @mloza1 - I see well this looks different from the issue I am investigating, but maybe I can still help.
There are 10s of thousands of changes between linux-image-5.15.0-25 and linux-image-5.15.0-67 so it's difficult to know what caused this. I think bisecting the changes is our best bet. Maybe you can try to narrow down which Ubuntu kernel started to fail this use-case? If you can find out which kernel version exactly started to fail that would be helpful.
