 ISTR there is a bit you can clear in the bus bridge to stop SERR from
 being forwarded upstream?  PCI_COMMAND_SERR_ENABLE, is it?
 It would be interesting to see the PCI Status Register on pci0 before
 and after the probe of 000:29:0.  Likewise, I'm curious what the PCI
 Command & Status Registers on 000:29:0 contain.
