Your patch avoids sizing transparent bridges. I don't have an opinion on whether that's a good idea in general.
However, I am curious about what breaks on your system when we do size the transparent bridge. It seems like sizing it should *work*, even if it's not strictly necessary, so I wonder if this hang is telling us about some other PCI allocation issue we should fix. Would you mind opening a bugzilla for this, since the current tree is broken for you, and attaching a log or digital photo of the hang?
