------- Comment #1 from htejun@gmail.com  2008-06-20 16:30 -------
Please provide more information.  What kind of machine is this?  What do you
mean by "compiled as module" - if ahci is built into the kernel, it's okay? 
Also, please attach kernel boot log.

-It's a notebook from a Brazilian vendor (Itautec S.A.).
-When ahci is built into kernel the machine shutdown. All okay.

What does exactly happen on shutdown if ahci is built as module?  What are the
last words of the kernel?

I tried to get theses info. But the system only show the services stopping on
shutdown. Could you help me?

ps: I made a Magic SysRq reboot and the machine rebooted ( with ahci as
module). I didn't have time to look this at kernel source, but I will do.

So, it hangs while stopping services?  Does it say anything about stopping
disks and powering off?

That message isn't from the kernel.  It's from shutdown script.  Are you sure
it's a kernel problem?  Does "halt -f" work?

 Are you sure it's a kernel problem?
I think that for system doesn't mind if ahci is built-in or module. So the
problem must be on kernel.

Does "halt -f" work?
No. The kernel says:
md:stopping all md drivers
sd 1:0:0:0: [sdb] Synchronizing SCSI cache
sd 1:0:0:0: [sdb] Stopping disk

These are the last words of kernel. And the machine stay on.

Sorry for delay on answer.

I Noted that the kernel take a infinite loop into device_shutdown()
(driver/base/core.c) when ahci compiled as module. I put dev_emerg on it and
saw the loop always showing "sd 0:0:0:0: shutdown".

I didn't have time to study about netconsole, but I will do.

Cc'ing Greg.  Gustavo is reporting that the kernel falls into an infinite loop
during shutdown if ahci is compiled as module (built-in works fine) and calls
sd shutdown indefinitely.  Does anything ring a bell?  Thanks.

Gustavo, can you please add the following loop at the top of device_shutdown()
and report what the kernel says?

  printk("XXX head prev=%p next=%p\n", devices_kset->list.prev,
devices_kset->list.next);
  list_for_each_entry(dev, &devices_kset->list, kobj.entry)
      printk("XXX prev=%p next=%p\n", dev->kobj.entry.prev,
dev->kobj.entry.next);

------- Comment #15 from gfpadovan@gmail.com  2008-08-01 13:00 -------
The dev->kobj.entry.prev and dev->kobj.entry.next point to same place. But I
noted that it isn't the one. This happens with other devices too.

So I tried whit this:

list_for_each_entry(dev, &devices_kset->list, kobj.entry) {
                dev_emerg(dev, " dev=%p prev=%p next=%p\n", dev->kobj.entry,
                dev->kobj.entry.prev, dev->kobj.entry.next)

And the unique dev that dev->kobj.entry, dev->kobj.entry.prev and
dev->kobj.entry.next point to same place. So we take an infinite loop.

Where is the function that include the device on the list? Is 
device_initialize()?

If my English is bad, ask me to rewrite this.

------- Comment #16 from tj@kernel.org  2008-08-02 22:00 -------
Eh... devices_kset list is corrupt?  Strange.  It's added through
drivers/base/core.c::device_add() -> lib/kobject.c:kobject_add() ->
kobject_add_vargs() -> kobject_add_internal() -> kobj_kset_join() ->
include/linux/list.h::list_add_tail().

So, it seems loading ahci as module breaks the list.  Strange.  The list is
manipulated only through device_add() and device_del().  Can you please put
some tracing code there and see what's going on?  (ie. printk to print out
what's happening followed by infinite loop check)

Can you please full kernel log?  Somehow it tried to add the same device twice
(or different devices with the same name) and apparently error handling in
duplicate case is incorrect.  Thanks.

Hmmm... Does disconnecting the card reader fix the problem?

Sorry about the long delay.  Can you please post full kernel log w/ the card
reader removed.  It seems usbstorage is trying to register the SCSI device used
by the card reader.  Thanks.
