http://bugzilla.kernel.org/show_bug.cgi?id=11884 Method(\_SB._INI) { //initialize package CUZO } Method(\_SB_.PCI0.LPCB.EC0_._REG) { //access package CUZO } For this machine, \_SB._INI must be run before \_SB_.PCI0.LPCB.EC0_._REG But currently early EC _REG method is run before _INI as below acpi_bus_init shows. void __init acpi_bus_init(void) ..... status = acpi_ec_ecdt_probe(); /* Ignore result. Not having an ECDT is not fatal. */ status = acpi_initialize_objects(ACPI_FULL_INITIALIZATION); ..... } acpi_ec_ecdt_probe will install ec handler although no ECDT found in this machine. Alexey, How about that if there's no ECDT found, we do not install ec handler before acpi_initialize_objects?
