kernel output after resuming

Will you please attach the output of acpidump?
It will be great if you attach the output of lspci -vxx before and after suspend/resume.
Thanks.

lspci output after resuming

The difference seems to be in the libata area as far as I can see.

Hi, Johannes
   Will you please attach the output of lspci -vxxx(not lspci -vxx) before and after suspend/resume?
   I am sorry for my fault.
   thanks.

Hi, Johannes
   Will you please try the early version kernel(for example: 2.6.24.3) and see whether the system can work well after resuming?
   It will be great if you can confirm whether the windows can work well after resuming from S3?
   Thanks.

Hi, Johannes
    Will you please add the boot option of "libata.noacpi=1" on the 2.6.27-rc6 kernel and see whether the problem still exists?
   thanks.

I can try later, but first I want to let you know about some new thing: I found out that it is apparently connected to the status of my dvd drive: If that is plugged in, everything works fine. If not, the described behaviour occurs.
To clarify I will attach the output of lspci -vxxx after resuming without the drive and the output after connecting the drive.

can you please try this patch set?

At runtime, can you check if hotplug dvd drive work?

As far as I can see everything works perfect using that patchset (especially battery hotplug is nice :))
Inserting the drive gives:

Hi,

I'm affected by this bug as well, on a Dell Latitude D610:
With the DVD drive in the media bay => no problem
Without the DVD drive in the media bay => kacpid + kacpi_notify using 100% CPU after resume.

I can help with testing a patch targetted at 2.6.27, if needed.

Hi, Lucas
    Please try the patch set as what Shaohua said in comment #13.
    thanks.

linus' git tree fails to build with the patch:

  Building modules, stage 2.
  MODPOST 2109 modules

I would be easier if you had a git repo I could pull from.

Did you apply the whole patch set or only one patch?

all of it, AFAIK. There were some conflicts that I had to solve manually.

please add "EXPORT_SYMBOL(acpi_os_hotplug_execute);" below the definition of acpi_os_hotplug_execute.

it works fine with the patch (after adding EXPORT_SYMBOL). I tried to suspend/resume 3 times.

What's the next step to get it into 2.6.27?

actually, a few minutes after resuming, my touchpad, and some of my keyboard's keys, stopped working. so something might still be broken.

a refreshed version of the patch series mentioned in comment #13
is included in the acpi-test tree, and linux-next tree,
staged for 2.6.28-rc1.

shipped in linux-2.6.28-rc1
