    If it has sysrq compiled in as root just do:

    echo s > /proc/sysrq-trigger
    echo u > /proc/sysre-trigger
    echo s > /proc/sysrq-trigger
    echo b > /proc/sysrq-trigger

    This will "sync", "umount/remount read-only", "sync", "immediate hardware
    reboot". Should always work...

    Best regards,
