Can either Pavel or Andreas please try this little debugging patch and
send me the dmesg output?  Please enable the CONFIG_DEBUG_KERNEL option
in your .config as well so that I can get additional info.

Len (or anyone),
I had a theory that perhaps I'm having a race condition between the two
drivers, however, I'm not sure if this is even a possibility at boot
time, so I wanted to run this theory by you and see if you thought it
could happen.  

The dock driver calls acpi_walk_namespace to check for _DCK method.
When it finds it, it allocates a struct dock_station, and then calls
acpi_walk_namespace again to find all the dependent devices.  This is
all done as part of the dock driver's init.

When acpiphp driver is called, it also calls acpi_walk_namespace to
check for pci devices dependent on the dock station.  It calls a
function exported from the dock driver (is_dock_device) to determine
this.  is_dock_device should only be called *after* the dock driver is
finished it's init, because the driver *must* have completed it's search
for dependent devices before it can answer the question
is_dock_device()?.  

My understanding is that if your init routine is marked with the
module_init() macro, then all module init routines will be serialized
with respect to each other.  i.e., Can I expect that the function
indicated by module_init() would be completed before the function marked
by acpiphp's module_init() would be called?  How does the use of
acpi_walk_namespace affect serialization of the module_init?  Does it
allow the possibility that the acpiphp driver may enter it's module_init
before the dock driver has completed it's init?

Thanks,
Kristen

Yep, you were right... this debugging patch helps.

No, I would not expect PCI to work properly with the debug patch -
basically all I did was prevent the oops and confirm that this is the
issue, I did not actually solve the problem.

I need some way to prevent acpiphp from loading before dock is completed
it's init.

I guess I will think about this some more.

Using different _init levels? Like putting dock at subsys_initcall()
while acpiphp at late_initcall()?

Can you see if this works for you?  Revert the first debug patch I sent
and apply this one instead (against -mm).

Thanks,
Kristen

Tried it in 

VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 17
EXTRAVERSION =-rc4-mm3

...and now kernel hangs, last messages being:

pci_hotplug: ... core version: 0.5
ibmphpd: ... 0.6
acpiphp: ... 0.5
acpiphp: Slot [1] registered

I tried hitting magic sysrq, but it did not seem to respond.

Would there be a problem if the init for acpiphp ran
before the init for dock started?

(no, I don't think that use of acpi_walk_namespace
 would/could have any effect on the order)

I don't know if we have tight controls on module load order.
IIR it depends on the link order in the makefiles for
static modules, and the init scripts for loadable modules.
