I got from Dennis Danielson his kernel configuration. He had the same problem at pemstar which is a dotcom. # # ACPI (Advanced Configuration and Power Interface) Support # CONFIG_ACPI=y CONFIG_ACPI_BOOT=y CONFIG_ACPI_INTERPRETER=y # CONFIG_ACPI_SLEEP is not set CONFIG_ACPI_AC=y # CONFIG_ACPI_BATTERY is not set CONFIG_ACPI_BUTTON=y CONFIG_ACPI_FAN=y CONFIG_ACPI_PROCESSOR=y CONFIG_ACPI_THERMAL=y # CONFIG_ACPI_ASUS is not set # CONFIG_ACPI_TOSHIBA is not set CONFIG_ACPI_BLACKLIST_YEAR=0 # CONFIG_ACPI_DEBUG is not set CONFIG_ACPI_BUS=y CONFIG_ACPI_EC=y CONFIG_ACPI_POWER=y CONFIG_ACPI_PCI=y CONFIG_ACPI_SYSTEM=y CONFIG_X86_PM_TIMER=y I tested this and so far have not seen that sluggish state since the kernel with the above ACPI configuration is running. -- Tapio Lehtonen Tapio.Lehtonen@IKI.FI GPG public key from http://www.iki.fi/Tapio.Lehtonen
