Hi Len and Rafael, With 3.7-rc3, I'm seeing a constant stream of these errors in the kernel log for my MacBook Pro: [30443.430133] ACPI: EC: input buffer is not empty, aborting transaction [30443.430145] ACPI Exception: AE_TIME, Returned by Handler for [EmbeddedControl] (20120913/evregion-501) [30443.430162] ACPI Error: Method parse/execution failed [\_SB_.PCI0.LPCB.EC__.SMB0.SBRW] (Node ffff88045cc64618), AE_TIME (20120913/psparse-536) [30443.430179] ACPI Error: Method parse/execution failed [\_SB_.BAT0.UBST] (Node ffff88045cc64988), AE_TIME (20120913/psparse-536) [30443.430188] ACPI Error: Method parse/execution failed [\_SB_.BAT0._BST] (Node ffff88045cc648c0), AE_TIME (20120913/psparse-536) [30443.430202] ACPI Exception: AE_TIME, Evaluating _BST (20120913/battery-464) They never showed up before in 3.7-rc2. Anything I should try out to resolve this? thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
