Hi.
I am also experiencing this issue on Gigabyte GA-M720-US3 mobo which uses
NVIDIA nForce 720D chipset. As I understand from the quirks patch it does not
fix my controller?

$ bunzip2 -ck dmesg_nForce_720D.txt.bz2 | grep 0x010601
[ 0.299980] pci 0000:00:09.0: [10de:0ad4] type 00 class 0x010601

In addition to the absense of devices during boot it takes minutes for this PC
on 5.15 to proceed from loading initramfs image to starting system from it.
I am attaching my dmesg just in case.

Max.
