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.

Still no clues. Could you post 'lspci -vvv', 'cat /proc/ioports' and
'cat /proc/iomem' outputs from working kernel?

the output is attached.
I saw a strange problem with ehternet too.
After booting the bad kernel and reboot the good kernel,
the ethernet doesn't work anymore. Multiple reboot, power off,
trying older kernel 2.4.27 didn't help. Pulling the power cable
fixed the problem.
I am prepared to do tweaks to your small patch, but I need your help.
My own blindly experiments failed miserably.

I don't think that patch did anything wrong, most likely it just
triggered a bug elsewhere. These two lines from your dmesg look
very suspicious:

Note that the BAR seems to have high address bits hardwired to fec00000.
And device 0000:00:04.0 is

I'd guess that when we try to reassign this resource, PCI interrupts might
just stop working. This could explain SCSI timeouts and other weird things.
Maybe this patch helps?

bingo, this works.
If it makes sense, please send this to Linus.
Thanks a lot,
