I think this is more likely an ACPI or dock driver problem than a
PCI problem, but I know very little about docks.
I think it's different from the problem you found on the mailing
list, so can you please open a kernel bugzilla report at
http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI
and attach your dmesg, lspci, and acpidump? Please respond to this
thread with the new bugzilla URL.
Thanks,
Bjorn

Ping, did you make any progress on this?

Hi Bjorn,
Thank you for the ping. : )

None, I am afraid. In the mean time I have unsusbscribed from the linux-{acpi,pci} lists, so please CC me.

I first thought this was an ACPI or dock problem, but I now think
this is a PCI issue after all, since the machine was booted in the
dock and no dock/undock events are involved.

It looks like the dock PCI slot should appear as 0b:00 (as it does in the
report at http://lkml.indiana.edu/hypermail/linux/kernel/0607.0/1409.html).
We do see the CardBus bridges in the dock. The fact that we don't see the
video card, which should be on the same bus, makes me suspect that the
dock's PCI slot is bad.
