Thanks. Could you please run memtest on this machine just to rule out a hardware issue, following the instructions at https://help.ubuntu.com/community/MemoryTest?

If that is ok, then can you recall the last known working kernel? If you can, would you mind performing a git-bisect, using the following guide: http://www.kernel.org/doc/local/git-quick.html#bisect. You can get the Jaunty git tree from git://kernel.ubuntu.com/ubuntu/ubuntu-jaunty.git

Well... "Murhys laws", Memtest found an error but rather late in step 3.

I then rotaded my memmodules and run it again 2 rounds without errors.

I installed Ubuntu-server because of broken manual-partition so I have no other kernels.

Nevertheless I started Kernelcheck for 2.26.29 and I got huge memory rush/leakages...... 400 > 900MB directly and then slowly up.

I am also using a swap-file... maybe aso a challenge ????

A reinstall is faster then messing with this... ;)

Latest udev update seems to make things much better... ;)

Compiling a kernel and memory usage is constant around 600MB....

(landed in a Firefox mess after upgrade, no NM > must use recovery > root network > init 5.... ;)

[plun (plun)]

Well... clean install daily build 32 bit, 14/1

Worked great for a while then the "Big bang"....

ntfs-config.... it might be a dirty bug there ???

(Memtest OK.....)

Not a sign with 2.6.30 and 2.6.31 kernels...
