TDA8954

I don't quite know where to post this, but I'm looking for some advice on the TDA8954. I have a circuit board with 2 devices, both of which are running in full-bridge mode. They are "cut and paste" designs: same exact schematic, same exact layout. One channel works and the other oscillates! I suspect there's something funky in the thermal design, but it may be exacerbated by the layout. Is there a reference design for this product that would show me recommended techniques?

Thanks for any help. If this isn't the right place to post this, please let me know that, too!
