    @zika: Do you have any idea what is the problem with this past -rc2 kernel and memory usage increase for active buffers?

    Sadly no. I've done complete clean-up, backup and reinstall (QQ>RR) yesterday. Now I have:
    Code:
    :~$ uname -a
    Linux zika 3.7.0-0-generic #5-Ubuntu SMP Thu Nov 8 20:58:16 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
    :~$ free -m
                 total       used       free     shared    buffers     cached
    Mem:          3954       3584        370          0        165       1747
    -/+ buffers/cache:       1671       2282
    Swap:         4093          0       4093
    Code:
    :~$ uname -a
    Linux zika 3.6.0-6.dmz.1-liquorix-amd64 #1 ZEN SMP PREEMPT Thu Nov 8 19:51:13 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
    :~$ free -m
                 total       used       free     shared    buffers     cached
    Mem:          3953       1202       2750          0         35        496
    -/+ buffers/cache:        670       3282
    Swap:         4093          0       4093
    (Liquorix is just brought up, I'll post change after couple of hours...)

    Later:
    Code:
    :~$ free -m
                 total       used       free     shared    buffers     cached
    Mem:          3953       1507       2445          0         39        540
    -/+ buffers/cache:        926       3026
    Swap:         4093          0       4093
    It stabilized:
    Code:
    :~$ free -m
                 total       used       free     shared    buffers     cached
    Mem:          3953       1674       2278          0         62        630
    -/+ buffers/cache:        980       2972
    Swap:         4093          0       4093
    (It seems to grow irrespectively of which kernel is used... But, there is a significant difference...)(It, also, might have to do with FF that was the only important application open during this time. There is a complaint that FF is leaking memory, as far as I recall...)

    Works!

    Code:
    vindsl@Zuul:~$ uname -sr
    Linux 3.7.0-030700rc6-generic
    But, I'd be willing to swear, "network-manager" is getting flakier with each new rc

    For instance, when I click on the NM indicator (in the top panel) there is a box for enabling networking, and not much else. Mind you, "networking" is enabled, but it runs like grunt.

    If I check "Enable networking" it sends me a notification that I just disconnected. Then, when I check "Enable networking" a second time. NM connects, and works fine for the rest of the session.

    Possibly, this is unrelated to the kernel, but I didn't notice it until the 3.7-rcs appeared... and I *think* it's getting worse. I could ignore it before. But, now, if I don't check the "Enable networking" box a couple of times, speeds are horrendous, my browser is slow and/or unresponsive, with 404s and so forth. Sometimes, I can't even log into machines on my LAN, in the next room, unless I go though this seemingly silly procedure.

    Maybe, I'll switch to Wicd for a while, and see if that helps...

    Memory leak that we expirianced is fixed in latest git.

    "fix incorrect NR_FREE_PAGES accounting (appears like memory leak)"

    3.7.0-3 2Acer Aspire1 netbook here, 1.6 gHz dual processors, 1 gb memory

    Not long afer booted up with Firefox 5 tabs:

    Code:
                 total       used       free     shared    buffers     cached
    Mem:           992        847        144          0         27        422
    -/+ buffers/cache:        397        594
    Swap:         1996         17       1979
    Memory pretty full not much swap used.

    After a while, not doing much,
    Code:
                 total       used       free     shared    buffers     cached
    Mem:           992        892         99          0         10        479
    -/+ buffers/cache:        402        589
    Swap:         1996        216       1779
    swap usage going up as the clock tics.

    Yeh, it could use more memory - one of the ways they got the price down to $250 was by simplifying the case - to add memory, remove keyboard, unplug and remove mother board, then have access to the memory and hard drive....not frustrated enough to try that yet.
