>> [ 227.525937] ACPI Exception: AE_TIME, Returned by Handler for [EmbeddedControl] (20110623/evregion-478) >> [ 227.525946] ACPI Error: Method parse/execution failed [\_SB_.PCI0.LPCB.ECDV.ECR1] (Node ffff880128e7a3d0), AE_TIME (20110623/psparse-536) >> [ 227.525957] ACPI Error: Method parse/execution failed [\ECRB] (Node ffff880128e7a268), AE_TIME (20110623/psparse-536) This appears to be fixed, or at least worked around, by Debian's kernel 3.1.5-1. My idle battery time doubled (yay!). Turbostat indicates that the CPU is now entering the higher-numbered "PC" states, which it wasn't doing beforehand. Thanks a lot to whoever fixed this issue. -- Juliusz Chroboczek -- 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
