    Phoronix: Samsung Laptops Will Soon See Better Linux Performance, Less Bugs

    The performance of several different Samsung laptop models will soon improve under Linux thanks to an important kernel fix that will appear in the Linux 3.15 kernel. This important patch addresses some ACPI issues and system performance issues for multiple Samsung laptops that have plagued Linux for at least two years...

    The fix to the reported bug is removing the battery and hitting the reset button...
    and they are *still* selling mobile phones with sealed batteries (yes, I know we are talking about laptops here)

      Ultimately we WANT low power state (I'm not sure about s3 since there maybe new power states that were defined fit just this purpose with the new acpi) interrupts so we can still do work. I know Linux isn't quite ready to do this but I wanted to mention it.
      The question is, of windows is dumping the buffer why was it ever filling it to begin with? Is this simply a faulty design?

        Yes.

        Lots of trouble with Samsung laptops, even on Windows. I've been experiencing all kinds of problems on 4 models recently, some seem to relate to this.

        I have a simpler solution to this problem that I like better: Don't buy Samsung laptops. They are all shit.

          I'm not sure I follow. S3 is suspend-to-ram, I don't see why the OS should care about recorded events in the EC in that case (i.e. IMO the buffer should be flushed in SMM by the firmware when going out of S3, not by the OS, so IMO it really isn't a problem with Linux). What do you mean when you say "Linux isn't quite ready to do this"?

              So you broke the bottom part to open the laptop ?

              I was about to do the same, cuz it gets frustrating, but there're plenty of youtube videos showing how to open them.

                As I said "perhaps not s3" (I simply don't recall the names and functions of each power state...that said, WoWlan can be triggered while in s3 and, in samsung's case, that signal may be passed through the ec). What I'm referring to is the fairly new ability for windows to engage in what they call connected standby (http://www.eightforums.com/tutorials...dows-8-pc.html).
                I think it was matthew garrett that spoke about this some time ago on his blog.
