This entry is being used for tracking a regression from 2.6.26. Please don't
close it until the problem is fixed in the mainline.
Please attach the full dmesg output.
Please attach the acpidump output using the latest pmtools at:
Sounds like a BIOS/ACPICA problem.
Re-assign to Ming.
Will you please confirm whether the system is affected by the warning message or the warning message is harmless?
From the acpidump it seems that this warning message is related with the BIOS. The package count of _PSS object is set to 0x03. But the BIOS give the incorrect package length.
> Name (_PSS, Package (0x03)
It's not a bug.
It just prints an error message because the declared package length does not match the actual length of the package.

I'm not sure if it's related but suspend to ram stopped working - my computer reboots on resume... (I noticed it today)

Ming, what's your plan of this bug?
do you think if an ACPI_ERROR is needed here?
The incorrect parameter is harmless in this bug.
change the ACPI_ERROR to ACPI_WARNING or ACPI_DB_INFO?
The s3 failure seems to be another bug.
Please file a new bug report about this. thanks. :)

change the ACPI_ERROR to ACPI_WARNING
Close it since it's not a bug.
Change the ACPI_ERROR to ACPI_WARNING for this case.
when will this patch hit mainline?
Well, I guess when Andi picks it up.
Lin Ming, please only close bugs when the patch has been merged. Otherwise we can lose track. Also please always add description and sign-off. Thanks
I'm not sure why this is tracked as a regression. Other than the harmless message
is there actually something broken?
I can merge the patch for test at least, but I'm not sure we really need it for .27
