The NULL pointer reference further down actually looks like something
foolish in the sysfs layer. But actually ACPI is not doing
anything wrong here I think. According to the backtrace it happens
when a kernel param (aka module_param) is set. And creating multiple
params in the same acpi space is completely legal.
It looks more like the high level code that sets up these parameters
broke somehow and starts registering these twice and now ACPI is the
first one to hit it (maybe because it starts with 'a' :-). Or perhaps
sysfs checking just got more anal and the params code relied on
being able to register duplicate directories?
Putting rusty into cc.

Perhaps we could try "acpi=off" and see if it still happens.

I doubt that would help because module_param()s are always registered
even with acpi=off. They are not really processed by ACPI, but by
kernel/params.c

Hi Randy,
care to add a printk to the module sysfs setup, and post dmesg again?
--- a/kernel/params.c
+++ b/kernel/params.c
@@ -603,6 +603,8 @@ static void __init param_sysfs_builtin(void)

name_len = dot - kp->name;

if (strlen(modname) != name_len
|| strncmp(modname, kp->name, name_len) != 0) {
I might show the order of registering the /sys/modules/ directory, and
if there is possibly another "acpi" section, which tries to add
parameter names.
Thanks,

Two different "modules" use the same prefix, which does not work with
the current logic, they need to live next to each other in the sequence
of options.
This adds a new option:
http://git.kernel.org/?p=linux/kernel/git/sfr/linux-next.git;a=commitdiff;h=1382827e93799ec07790849e361267993cfe549e
which specifies MODULE_PARAM_PREFIX="acpi." in:
drivers/acpi/power.c
In the same way as:
drivers/acpi/system.c
Seems, two different modules should not declare parameters in different
locations, and use the same MODULE_PARAM_PREFIX.
Thanks,
Kay

Sequence of options being defined by link order?

That seems bogus to me. Assuming we have some code in a module and then split
it out into two different modules. Or move an option from one file to another.
Would we need to change the option name then?
I think the generic params code should be fixed to handle this.

Yeah, they are stored in a global array __start___param, and the current
code expects the prefixes to be sorted, so the sysfs directories can be
created for every first new prefix.

They have been module options, not prefixed kernel parameters so far,
and the prefix was just the module name.
So it just strikes back, that acpi uses generic names for the modules,
there would have been no problem if "power" would be called "acpi_power"
and the options would just be "acpi.acpica_version" and
"acpi_power.nocheck".
But well, there are driver modules just called "option", so acpi is not
that bad. :)
> I think the generic params code should be fixed to handle this.
We could try to look up existing directories to use instead of expecting
that we need to create and own them. I guess, we have the same issue if
we compile the code as a module and load it later, while some other
built-in code or module has already used the same prefix.

Simplest fix is to shuffle Makefile. But better is to create an acpi "module"
so the namespacing just works, something like below. Overriding MODULE_PREFIX
only works for builtin code anyway. (Which makes sense: moving a parameter
from one module to another isn't a change we can cover up).

sysfs does this anyways, doesn't it. We would just need to teach it
to not BUG() in this case, perhaps with a special entry point.
Also a BUG() in general seems a little harsh for this, surely a WARN_ON
should be enough.

Can't say I like this. This is fragile. I can just this exploding the next time

It is a WARN() call, not a BUG().

Ah, missed that. Thanks Sam!
I had another bug: if both options were off, compile would fail. Put
everything in acpi.o to fix this.

Ok. Can we remove it? Or add a new entry point that allows to disable it?
I don't think relying on link order like Rusty proposes is a good long term

No!
What you are doing here is wrong, trying to create two files with the
same name. You just should not be doing that at all, it's that simple.
Fix the broken code/link order, don't paper it over in the sysfs layer.

Sorry, but relying on link order for anything is a mistake. It is subtle
and fragile and just means it'll eventually break again because it's
near impossible to properly maintain.
The alternative is to always check if the file exists in the params.c
code before creating it. We can do that too, but it's somewhat dumb
because sysfs is already doing that.

To be clear, I agree with Andi. If this is for current kernel I'd just fix
link order, for longer term we need something cleverer.

We rely on link order for all sorts of things, this isn't new at all.

Sure, but this code should be rewritten to check if the directory exists,
rather assuming it based on "previous prefix was the same".
It's relying on a horribly undocumented assumption, and it broke.
We need to change kernel_param_sysfs_setup() to do something
like "kobject_find(module_kset, name)" and only allocate a new mk if that
fails. Then we need to change the code to allow appending, like below.

kobj = kset_find_obj(module_kset, name) should return an existing object
with that name (and take a reference on it, which needs to be dropped).

I think we (all) agree that we should keep the acpi gunk together,
rather than creating namespace sprawl to satisfy the current sysfs code.

This problem first shows up with the addition of the
acpi.power_nocheck modparam, which is staged for 2.6.28.
Is 2.6.28 "current" or longer term?

There's a proper fix in linux-next for 2.6.28. I was unclear about whether
this ACPI change was going into 2.6.27; since it's not, there's no real
issue.
Hope that helps,
Rusty.
