Hi Lars,

I have tested the kernel

'Linux lubuntu 3.11.0-7-generic #14~lp1227202v1 SMP'

last night and this morning. I tested it as an installed system running
in my Toshiba giving it only 384 MB RAM. I alternated between this
kernel and the default one. I made it swap, for example running some
youtube video. Then if I installed something with apt-get, I often had
freezes with the default kernel but never with the #14~lp1227202v1 kernel.

You result contradicts my result, and it is stronger, because I cannot
guarantee, that there will be no freeze in the future.

I noticed a significant improvement with the bug-fix in the
#14~lp1227202v1 kernel, but maybe there is also some other problem
causing the computer to freeze. This problem might or might not be
related to zRAM, and that can be explored testing when the zRAM is
switched off.

Best regards
