Distro is Mandriva Linux Cooker, and arch is x86_64
Attached is output of "grep ACPI /var/log/dmesg"
dmesg-acpi-20090903
- all acpi patches as of 2.6.32-rc1
I should have done dmesg|grep ACPI to get the errors... it would have shown this too:
tg3 0000:02:00.0: wake-up capability disabled by ACPI
ACPI Exception: AE_TIME, Returned by Handler for [EmbeddedControl] (20090903/evregion-424)

Isn't that what pretty much what I did when I built a kernel with the 2.6.31.1 ec.c ?dmesg-acpi-20090903-ec-2.6.31There is only one patch which touch ec.c, 2a84cb9852f52c0cd1c48bca41a8792d44ad06cc. You may try to revert it, and see.
- all acpi patches as of 2.6.32-rc1
- ec.c from 2.6.31.1
Should I start bisecting, or do you have any other suggestion?
Anyway, after I applied your patch you just posted on acpi-devel:
ACPI: EC: Rewrite DMI checks
to the 2.6.32-rc1 tree the:
-ACPI Error (psargs-0359): [\_PR_.CPU0.CSTX] Namespace lookup failure, AE_NOT_FOUNDdoes not show up at boot anymore, and so far I haven't seen the other errors either...
-ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.PCI0.LPCB.EC0_._Q2F] (Node ffff88013f81c1a0), AE_NOT_FOUND
I'll post a follow-up if they show up again...
I spoke too soon:
That generated a big log......
This is now grep ACPI /var/log/syslog from the 2.6.32-rc1 + the above "ACPI: EC: Rewrite DMI checks"
As it's big, I posted it here:

please check if attached patch helps:
