    Phoronix: The Linux 3.0 Kernel Will... Reboot Better?

    Beyond file-system cleancache support, a Microsoft Kinect driver, Intel Ivy Bridge support, and various open-source graphics driver improvements, the Linux 3.0 kernel may also reboot your system better. Yes, really...

    second why is it bad that it points @ 0xcf9? would be 0x1337 more appropriate?

    and what's the big deal about poking the keyboard controller? If I want my PC to reboot I want it to reboot. It should not poke itself o_0

    That's like saying your going to sleep and then, just before sleeping you masturbate. oh wait...
    If you read the blog post, you'll find out why they point to 0x0CF9. It's bad because it's an undocumented feature, not standardised, and strictly speaking requires a pair of magic words, though appears to work with only one written twice. That's how I read it anyhow.
    Basically the way to signal a reset/reboot to the system is about as murky and abhorrent as the wireless mbus standard.

    Sadly, broken hardware (or broken BIOS that causes broken-hardware-like behavior) is the safe bet when it comes to PC. Perhaps not for any specific piece of hardware, but for a randomly-chosen PC there's a good chance that it has at least one quirk calling for a similarly ugly workaround. If the workarounds were all configurable, configuring a custom kernel would go from "slightly tedious" to "black art".

    good to see the boot/reboot behavior finally getting some love in the linux desktop.

    with this and what systemd brings am becoming much happy.

    say to you?

    Without the context given by the original blog post this are just words clung together. Random quotes from blogposts you dont understand don'tmake for a good article.

    I sometimes wish Michael would just syndicate these blog posts into his site rather than trying to rewrite them. Articles on phoronix should be thought out researched and infromative, not a link fest with the words "leveraged" and "etc." added.
