I have this problem only since upgrading to 2.6.25 - it isn't there with 2.6.24
which I am using now (I downgraded).
Where do I find linux-2.6.25-git16 mentioned above?

Additional info for above - it only occurs when I have resumed from disk after
having hibernated using s2disk. On a normal boot it doesn't happen.

Hi, Ben
   Maybe the problem of your laptop is different with this bug.
   Will you please open a new bug and attach the output of dmesg, acpidump,
lspci -vxxx?
   Thanks.

I believe the culprit in my desktop board d945GCNL. I fount in net that there
is ACPI problem with this board when installing windows 2000. There is a BIOS
update which fixes this. I installed it but no luck. It does'nt fix for linux!
After the update i found something in dmesg. I do not know if it is of any help

intel_rng: Firmware space is locked read-only. 4intel_rng: If you can't or
 don't want to 4intel_rng: disable this in firmware setup, and 4intel_rng:
if
 you are certain that your 4intel_rng: system has a functional
 RNG, try4intel_rng: using the 'no_fwh_detect' option.

--- Comment #12 from [EMAIL PROTECTED]  2008-03-13 18:26 ---
Thank for the info.
Now it is confirmed that the bug is caused by the ACPI interrupt flood. And
the GPE 0x1D is triggered at very high rate. (In fact there is a similar bug
9781)

On this desktop the GPE 0x1D is a wakeup GPE and shared by three device :
Sleep button, PS2K, PS2M. And GPE 0x1D will be configured as Run_Wake(Runtime
wakeup) gpe in button driver. 
According to ACPI spec the wake events should not be intermixed with
non-wake (runtime) events on the same GPE input. In this desktop the wake
events are intermixed with the non-wake(runtime) events on the same 0x1D gpe
input. It is incorrect.

Thanks.

Well, this is a duplicate of bug 9781.
The problem is caused by a violation of ACPI spec.
The patch in bug 9781 can not be upstream as it's just a work around.
The most important thing for us is to make clear why it works in Windows, and
why boot after a windows boot changes the symptom in Linux.

try the debug patch

Will you please try the debug patch and see whether the problem still exists?

In this patch OSPM will call _PSW method to disable the device's ability to
wake up the system. 
Thanks.

What Rui said in comment #15 is right. The problem is caused by the violation
of ACPI spec. 

Will you please try the debug patch in comment #17 and see whether the problem
still exists? Please add the boot option required in comment #1 and attach the
output of dmesg.
Thanks.

 The problem was there for both kernels.
clearing regression flag on this report, as apparently this
problem happens with all kerenls that run on this machine.

in addition to the questions above...

running 2.6.25, please paste the output of this command:

grep acpi /proc/interrupts; grep . /sys/firmware/acpi/interrupts/*

 Latest working kernel version:2.6.24
 Earliest failing kernel version:2.6.22

I will assume that these were reversed.  That 2.6.22 works OK and that
2.6.24 does not.

Sorry my mistake. The problem was there for both kernels. In my old hardware
there was no such problems which ever kernel i used.

Hi, Jithin
It seems that the problem is related to acpi interrupt floods.   
Will you please enable the ACPI debug function in kernel configuration and
boot the system with the option of acpi.debug_layer=0x010004
acpi.debug_level=0x817 ?

After the system is booted, please attach the output of dmesg and
/proc/interrupts. 
It will be great if you can attach the output of acpidump.

Thanks.
