Hi all, The following message is displayed on our server(PRIMEQUEST): ACPI: bus type pci registered ACPI: EC: Look up EC in DSDT ACPI: BIOS _OSI(Linux) query ignored ACPI: DMI System Vendor: <NULL> ACPI: DMI Product Name: <NULL> ACPI: DMI Product Version: <NULL> ACPI: DMI Board Name: <NULL> ACPI: DMI BIOS Vendor: FUJITSU LIMITED ACPI: DMI BIOS Date: 1/17/2008 ACPI: Please send DMI info above to linux-acpi@xxxxxxxxxxxxxxx ACPI: If "acpi_osi=Linux" works better, please notify linux-acpi@xxxxxxxxxxxxxxx Because "acpi_osi=Linux" boot option works well, so we want to use _OSI(Linux) query on PRIMEQUEST without this boot option and inihibit above message. I thought the way to achive our goal was to add the following entry to acpi_osi_dmi_table (at drivers/acpi/blacklist.c), { .callback = dmi_enable_osi_linux, .ident = "Fujitsu PRIMEQUEST", .matches = { DMI_MATCH(DMI_BIOS_VENDOR, "FUJITSU LIMITED"), }, } but unfortunately this table seems to be valid only for x86 machines. Our server is ia64, but what is the best solution? -- Regards, Taku Izumi <izumi.taku@xxxxxxxxxxxxxx> -- 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
