This bug has been copied from bug #519633 and has been proposed
to be backported to 5.4 z-stream (EUS).
Please do NOT transition this bugzilla state to VERIFIED until our QE team
has sent specific instructions indicating when to do so.
Have tested it on intel-s3e36-02.rhts.eng.rdu.redhat.com which has a 0000:ff
pci bus with following configurations:
i386 + 2.6.18-164.6.1.el5
i386 + 2.6.18-164.8.1.el5
and cannot reproduce it.
We may still need our partners to help us verifying this bug on Intel® TIGW1U with kernel 2.6.18-164.8.1.el5.
[root@dhcp-65-148 i386]# pwd
[root@dhcp-65-148 i386]# grep "pci_scan_bus(" * -rn
pci/common.c:546: bus = pci_scan_bus(busno, &pci_root_ops, sd);
pci/irq-xen.c:153: if (pci_scan_bus(i, &pci_root_ops, sd))
Could we also use the wrapper function instead of pci_scan_bus()?

That's where I implement the wrapper, please take a look at code, not just grepping code.
> pci/irq-xen.c:153: if (pci_scan_bus(i, &pci_root_ops, sd))
That's used in xen, and this bug is from sysdata is NULL, the comments in pci/irq-xen.c shows sysdata cannot be NULL here because of PCI_DOMAIN support.
Since this line is not buggy, why should we wrapper this?

In fact, I've viewed the code, although not as much as you guy. The grepped result is for your clarity. If you think it's ok, then just ignore here. Sorry for bothering.
