 I had a look at the code in current.
 
 The failing line in rbus_new_root_share() must be:
 if (start < ex->ex_start || start + size > ex->ex_end) {
 
 At that point, ex is NULL.
 
 Now, in rbus_pccbb_parent_io() [i386]:
 
 =09struct extent *ex =3D ioport_ex;
 
 #if defined(PCI_ADDR_FIXUP)
 =09if (pciaddr.extent_port !=3D NULL)
 =09=09ex =3D pciaddr.extent_port;
 #endif
 
 ...
 
 So there is a possibility that it might work with PCI_ADDR_FIXUP
 enabled. Can you please try this ?
