I have exactly the same issue according to everything you've described. Also running 20.04 with linux-image-5.15.0-125-generic 5.15.0-125.135~20.04.1
It works if I boot form the previous kernel version, linux- image-5.15.0-124-generic 5.15.0-124.134~20.04.1, so it seems like a regression in the linux-image-5.15.0-125-generic 5.15.0-125.135~20.04.1 kernel.
