Kernel 3.7-rc1

[Milos_SD]

@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:

(Liquorix is just brought up, I'll post change after couple of hours...)

Later:

:~$ free -m
             total       used       free     shared    buffers     cached
Mem:          3953       1507       2445          0         39        540

Swap:         4093          0       4093

It stabilized:

:~$ 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!

vindsl@Zuul:~$ uname -sr

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:

             total       used       free     shared    buffers     cached
Mem:           992        847        144          0         27        422

Swap:         1996         17       1979

Memory pretty full not much swap used.

After a while, not doing much,

             total       used       free     shared    buffers     cached
Mem:           992        892         99          0         10        479

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.
