    Feel free to take that up with upstream, we will not diverge for this.

    Sure, but how about when you try to type the actual ALT SYSRQ h?

  4. Bug#452246: sysrq h does not work now

    On my Thinkpad r50e, in tty1
    ALT SYSRQ SHIFT prints the help lines.
    ALT SYSRQ h doesn't.
    In /dev/pts/0 (icewm), both don't.

    Anyway, in states like bug 451989,
    SYSRQ didn't help and I had to hit the RESET button.
