    Re: Kernel 3.7-rc1

    I spoke too early. After 24h uptime, memory usage is almost doubled. Insted of normal 2.5GB usage, I have 4.52GB.

    Can You decode what is the memory „used“ for... I can not confirm such sort of growth... To be more precise: I can account every kind of growth to a service or application I've used... In other words I can not suspect any (major) memory leakage...
    I will try to use other kernel for the same amount of time and to see if I would notice any considerable differences...

    Code:
     free -m
                 total       used       free     shared    buffers     cached
    Mem:          7989       7563        426          0        146       2772
    -/+ buffers/cache:       4643       3345
    Swap:         1953        688       1264
    See that -/+ buffers/cache used? That should not be so much. And I can't account everything to applications and services. Not even half of that is used by apps and services. Even when I logout/login there is almost 4GB of usage.
    I know what buffers and cache are, but it doesn't behave like it should. If I start playing some game, I'm starting to get a lot of swapping and slowdowns because of it.

    P.S. I have very unique kernel configuration. I have PREEMPT+1000Hz+HugeTLB+RCU ...

    I'll keep my eye(s) on that... Will report if I see anything to report...
    (I have a sledgehammer tool for cleaning memory...
    Code:
    sudo sync ; sudo sysctl -w vm.drop_caches=3 ; sudo sysctl -w vm.drop_caches=1
    but I'm afraid that will not affect parameter You're watching...)

    Update: @MilosSD: It seems that You have a valid point... Confirmed...

    Re: Kernel 3.7-rc1

    I have tried over 4 different version of 3.7rc[1-4], none of which works normally. The system runs but without stability. At first it looks good, but after a while you may feel some different compared to 3.5 or 3.6. And also there are more fails in /var/log/kern.log. In my case the kernel specially has a thing on my ata hard drive, which results in low I/O performance. My opinion is kernel 3.7rc is far from being usable. I'm running Ubuntu 12.10 not 13.04, but I don't think it's relevant.

    Can everyone that have this bug with memory leaks, go here and confirm it:
    https://bugzilla.kernel.org/show_bug.cgi?id=50181

    Also, describe it better then me, please. My English s**ks.

    Thanks.

    Re: Kernel 3.7-rc1

    Some good news for those of us who can only use the legacy nvida driver now (i.e. latest nvidia-current does not support our graphics cards).

    Code:
    paul@raring-64:~$ apt-cache policy nvidia-current-updates
    nvidia-current-updates:
      Installed: 304.64-0ubuntu1
      Candidate: 304.64-0ubuntu1
      Version table:
     *** 304.64-0ubuntu1 0
            500 http://archive.ubuntu.com/ubuntu/ raring-proposed/restricted amd64 Packages
            100 /var/lib/dpkg/status
         304.51-0ubuntu1 0
            500 http://archive.ubuntu.com/ubuntu/ raring/restricted amd64 Packages
    paul@raring-64:~$
    With this version, the nvidia kernel module builds ok with kernel 3.7-rcN.
