This looks suspicious.  10ec is the vendor ID for Realtek, i.e. it
implies that the BIOS on this machine didn't give the proper unique
ID.  As you can see, the other entries with 10ec are only reference
boards.

If the newer BIOS still doesn't fix the PCI SSID, you can check the
codec SSID instead.
