Re: ACPI error during Sandybridge boot

Hi, Alexey

   The following warning message is complained on one box in the boot
phase. And the EC opregion field is accessed in the GPE L01 method.
After looking at the source code it seems that the GPE L01 is enabled
before installing EC space handler.

    There is no ECDT table in the acpidump. And there is no _INI object
for the ACPI EC device. 
    

Any idea about this issue?
    Can we also initialize the EC device and installing EC space handler
earlier as we have done on the machine with the ECDT table?

Thanks.
    Yakui
