Could you do a bisect?
In particular, please try the 2.6.31 versio of drivers/acpi/ec.c
Hi,
in order to get the 2.6.31 version of ec.c to build I had to apply a
small patch:
--- linux-acpi/drivers/acpi/ec.c.orig 2009-09-10 01:13:59.000000000

After that it built and the errors are gone.
Now this is a Acer TravelMate 5720G laptop with the latest 1.35 bios.
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
This one does not have errors you've mentioned earlier, could you find dmesg with them?
dmesg-acpi-20090903-ec-2.6.31
- 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?
There is only one patch which touch ec.c, 2a84cb9852f52c0cd1c48bca41a8792d44ad06cc. You may try to revert it, and see.
Regards,
Alex.
