Hi

Something broken with ACPI power profiles on recent (yesterday)
7-CURRENT

Below configuration, that always works fine for me, now lead to instant
screen brightness blinking while activity.

# cat /etc/devd/acpi_power.conf 
notify 20 {
        match "system"          "ACPI";
        match "subsystem"       "ACAD";
        action                  "/usr/local/etc/acpi_power $notify";
        action                  "/etc/rc.d/power_profile $notify";
};

# cat /usr/local/etc/acpi_power
#!/bin/sh

case "$1" in 
        0x01)
                sysctl dev.acpi_sony.0.brightness=8
                ;;
        0x00)
                sysctl dev.acpi_sony.0.brightness=2
                ;;
esac

Any hints about this case ?
