It is a problem with some bridges and PCI BIOS interrupt routing.

Maybe you could post it.  It makes sense if you have on-board PCI
devices.

Did it used to work when we were re-routing all the time?  It would be
easy to add this as an option, but maybe understanding your setup
might help a little to make our routing code a little smarter.
