State=ffff88012d70f800 (20110413/dswstate-98) ACPI Exception: AE_AML_NO_RETURN_VALUE, Missing or null operand (20110413/dsutils-646) ACPI Exception: AE_AML_NO_RETURN_VALUE, While creating Arg 0 (20110413/dsutils-763) ACPI Error: Method parse/execution failed [\_SB_.VALZ.GETE] (Node ffff880131175eb0), AE_AML_NO_RETURN_VALUE (20110413/psparse-536) ACPI Error: Method parse/execution failed [\_SB_.VALZ.INFO] (Node ffff880131175ed8), AE_AML_NO_RETURN_VALUE (20110413/psparse-536) toshiba_acpi: ACPI INFO method execution failed toshiba_acpi: Failed to query hotkey event All known machines with this implementation also have a WMI interface with event GUID 59142400-C6A3-40FA-BADB-8A2652834100 which is not seen on any other models. Refuse to load toshiba_acpi on machines with this guid. Signed-off-by: Seth Forshee Signed-off-by: Matthew Garrett --- Reading git-diff-tree failed
