2.6.21.1 problems during suspend-to-ram

2.6.21.1 problems during suspend-to-ram

Hi,

I'm trying to suspend my MacBook2,1 to ram and always get following error 
during suspend:

ACPI: PCI interrupt for device 0000:00.1f.2 disabled.

I'm suspending the maschine with sysfs (echo mem > /sys/power/state).
Did I forget to set a option?

Here are some additional informations:

That's not an error - what problems do you think it's causing?

I realy dont know... Maybe you can give me some hints?
Is there a way to get more debug info except enable debugging in the kernel?

Well, uh, to start with it might help if you actually told us what the 
problem is.

Main problem is, that the maschine is not shutting down (suspend consoles).
I tried s2ram and s2disk with both programs I'm not able to suspend my 
maschine. All devices (nic, firewire, usb etc) except hdd were suspended 
without any problems. After that the maschine freezes, showing this message:

------- 8< -------
ACPI: PCI interrupt for device 0000:00.1f.2 disabled.
------- 8< -------

As 00:1f.2 is my S-ATA controller, I think my harddisk will not get 
suspended...

------- 8< -------
00:1f.2 IDE interface: Intel Corporation 82801GBM/GHM (ICH7 Family) Serial ATA 
Storage Controller IDE (rev 02)
------- 8< -------

The only possibly way to suspend my system to disk is using sysfs.
But this also only works when I set /sys/power/disk to "shutdown".
If it's set to "platform" my system will not suspend.

So there must be a problem with ACPI. Am I right with this suspicion?

Probably, but the stack trace that you have quoted is likely unrelated to this
problem.

Please try the appended patch and see if you can suspend to disk in the
platform mode with it.

I applied this patch but suspend to disk still doesn't work in platform mode.
Any other ideas? Do you have a clue whats going wrong here?
If you need more infos or data please tell me.

No, I don't.

I think more information will be necessary to resolve this problem, but at the
moment I don't know which information will be relevant.

Could you please file a bug report at http://bugzilla.kernel.org, in the
ACPI->Power-Sleep-Wake category and add my address to the CC list?
