Here's the relevant ACPI error messages (with full ACPI debugging enabled) from acer_acpi, with some comments as to which method is being called and what arguments we're passing. This user tested this on Kubuntu Gutsy (7.10) x86-64, with a custom 2.6.23.9 kernel (basically, just the ACPI debugging enabled so we can get a better trace). So, for reference, this is the DSDT we're working with: http://files.strangeworlds.co.uk/5040.dsl WMCA(1, 3, NULL): [23375.726016] ACPI Error (evregion-0316): No handler for Region [RAM_] (ffff81000132d1a0) [EmbeddedControl] [20070126] [23375.726246] ACPI Error (exfldio-0289): Region EmbeddedControl(3) has no handler [20070126] [23375.726475] ACPI Exception (dswexec-0462): AE_NOT_EXIST, While resolving operands for [Store] [20070126] [23375.726708] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.AMW0.WMCA] (Node ffff8100013315f0), AE_NOT_EXIST WMCA(1, 6, BUF(4 bytes) = 1): [23444.490213] ACPI Error (evregion-0316): No handler for Region [RAM_] (ffff81000132d1a0) [EmbeddedControl] [20070126] [23444.490218] ACPI Error (exfldio-0289): Region EmbeddedControl(3) has no handler [20070126] [23444.490223] ACPI Exception (dswexec-0462): AE_NOT_EXIST, While resolving operands for [LGreater] [20070126] [23444.490228] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.AMW0.WMCA] (Node ffff8100013315f0), AE_NOT_EXIST [23444.490263] acer_acpi: In: 0x00000001 -Carlos -- E-Mail: carlos@xxxxxxxxxxxxxxxxxxx Web: strangeworlds.co.uk GPG Key ID: 0x23EE722D - 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
