Subject: regression on quad Xeon: no SCSI-disks
Sorry
for detecting this 2 year old regression so late.
2.6.13 or later is bad.
2.6.12 is good,
"git bisect" worked fine and points to the attached patch.
The patch is pretty small. The problem seemed to be dependant
on the PCI-architecture of these particular systems.
Tried this on two machines with the same behaviour.

[PATCH] PCI: pci_assign_unassigned_resources() on x86
- Add sanity check for io[port,mem]_resource in setup-bus.c. These
resources look like "free" as they have no parents, but obviously
we must not touch them.
- In i386.c:pci_allocate_bus_resources(), if a bridge resource cannot be
allocated for some reason, then clear its flags. This prevents any child
allocations in this range, so the setup-bus code will work with a clean
resource sub-tree.
- i386.c:pcibios_enable_resources() doesn't enable bridges, as it checks
only resources 0-5, which looks like a clear bug to me. I suspect it
might break hotplug as well in some cases.
