Hi, In 2.6.30 running on a Vaio SR19VN I receive bursts of messages like the following, consistently and periodically: [282755.328562] ACPI: EC: input buffer is not empty, aborting transaction [282755.328581] ACPI Exception (evregion-0422): AE_TIME, Returned by Handler for [EmbeddedControl] [20090320] [282755.328611] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.BAT0._BST] (Node ffff88013fa742d0), AE_TIME [282755.328780] ACPI Exception (battery-0385): AE_TIME, Evaluating _BST [20090320] [282755.836522] ACPI: EC: input buffer is not empty, aborting transaction [282756.336536] ACPI: EC: input buffer is not empty, aborting transaction [282756.336555] ACPI Exception (evregion-0422): AE_TIME, Returned by Handler for [EmbeddedControl] [20090320] [282756.336585] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.BAT0._BST] (Node ffff88013fa742d0), AE_TIME [282756.336757] ACPI Exception (battery-0385): AE_TIME, Evaluating _BST [20090320] [397784.536520] ACPI: EC: input buffer is not empty, aborting transaction [397784.536530] ACPI Exception (evregion-0422): AE_TIME, Returned by Handler for [EmbeddedControl] [20090320] [397784.536543] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.BAT0._BST] (Node ffff88013fa742d0), AE_TIME [397784.536607] ACPI Exception (battery-0385): AE_TIME, Evaluating _BST [20090320] This has actually been going on for a while now, at least since some of the early .30 rc's. It's not clear to me what it means or what the impact is.
