Software Environment:

Problem Description:

Every time I try to suspend my MacBook to disk (platform modus) I get following
message before the system freezes:

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

As 00:1f.2 is my S-ATA controller, I think that the harddisk can not be suspended.

If I change the suspend modus to "shutdown", The system will suspend without any
problems. But only to _disk_. To ram also fails with that option.

If you need more data/details to this problem please let me know.

PS: DISABLE_CONSOLE_SUSPEND is enabled.

Regards,

Marvin Stark
Comment 1 Rafael J. Wysocki 2007-05-02 11:17:44 UTC 
Have you tried with ENABLE_CONSOLE_SUSPEND disabled?
Comment 2 Marvin Stark 2007-05-02 11:50:59 UTC 
Yes, I did. Same result.
Freezing at "Suspending console(s)"
Comment 3 Luming Yu 2007-05-05 07:24:01 UTC 
>ram also fails with that option

Did you try s3 with old kernel such as 2.6.20?

Also I would suggest you to try linux firmware ready tool
http://www.linuxfirmwarekit.org/, and try s3 with that tool.

Yes I did. Also, same result.

Here Suspend to disk seems to work. But after opening the lid again, the screen
won't come back.

Maybe the are problems because my root partition is encrypted?
Comment 5 Rafael J. Wysocki 2007-05-24 09:52:11 UTC 
That would only affect hibernation, not S3.

Could you test 2.6.22-rc2?  There's one importand suspend-related change in it.

Yes it worked! The maschine suspends now. After reopening the lid the 
backlight turns on again but there's no screen. What's going wrong here?

Comment 7 Rafael J. Wysocki 2007-05-27 14:46:58 UTC 
Might be a couple of reasons, AFAICT.

Have you tried s2ram (http://en.opensuse.org/s2ram) ?

Yes, same result. I also tried with vbe_save and vbe_post.
s2ram version is: 0.3~cvs20060928-7
Comment 9 Rafael J. Wysocki 2007-05-28 11:16:49 UTC 
For now, I'm out of ideas. :-(
Comment 10 Rafael J. Wysocki 2007-05-30 08:52:52 UTC 
What happens if you boot the 2.6.22-rc3 kernel with init=/bin/bash and do:

# mount /sys
# mount /proc
# echo 5 > /proc/sys/kernel/printk
# echo platform > /sys/power/disk
# echo disk > /sys/power/state

?
Comment 11 Marvin Stark 2007-06-01 09:45:25 UTC 
Hi,

today I tested 2.6.22-rc3 and suspend-to-RAM worked like a charm!
Comment 12 Rafael J. Wysocki 2007-06-01 12:21:28 UTC 
Good news!

OK, so do you think we can close this bug?

Comment 14 Rafael J. Wysocki 2007-06-01 16:14:28 UTC 
Fixed in 2.6.22-rc3.
