Full dmesg from 3.9-rc5 with patch from bug 56501
On my Sony laptop, if I dock, undock and dock again, acpiphp_glue fails to
register interrupt notify handler and then the kernel dereferences the NULL
pointer in pci_bus_read_config_dword. The full dmesg (captured in part locally,
and in part over netconsole) is attached. The lines starting with
/sys/bus/pci/devices were written to /dev/kmsg for debugging another bug, you
can ignore them now.
Note: there are also failures to assign resources to PCI devices in the dock.
They might share the root cause, but are tracked in a different bug #56531.

such as dmesgs and acpidump output:
