    d'après sysrq.txt:

    * What are the 'command' keys?
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    'r' - Turns off keyboard raw mode and sets it to XLATE.

    'k' - Secure Access Key (SAK) Kills all programs on the current virtual
    console. NOTE: See important comments below in SAK section.

    'b' - Will immediately reboot the system without syncing or unmounting
    your disks.

    'o' - Will shut your system off (if configured and supported).

    's' - Will attempt to sync all mounted filesystems.

    'u' - Will attempt to remount all mounted filesystems read-only.

    'p' - Will dump the current registers and flags to your console.

    't' - Will dump a list of current tasks and their information to your
    console.

    'm' - Will dump current memory info to your console.

    '0'-'9' - Sets the console log level, controlling which kernel messages
    will be printed to your console. ('0', for example would make
    it so that only emergency messages like PANICs or OOPSes would
    make it to your console.)

    'e' - Send a SIGTERM to all processes, except for init.

    'i' - Send a SIGKILL to all processes, except for init.

    'l' - Send a SIGKILL to all processes, INCLUDING init. (Your system
    will be non-functional after this.)

    'h' - Will display help ( actually any other key than those listed
    above will display help. but 'h' is easy to remember :-)


    pour pouvoir utiliser ces combinaisons, il faut les avoir compilés leurs support dans le noyau (kernel hacking/Magic Sysrq key)
    il est possible de les désactiver grâce à un simple:

    echo "0" > /proc/sys/kernel/sysrq

    mais la meilleure des choses reste de lire la doc du noyau pour en savoir plus.
