Hi Lars,

1. Working system with zRAM

I have been running a system with the kernel that Joseph Salisbury gave
to us some week ago (3.11.0.7-generic #14~lp1227202v1 SMP Wed Sep 18). I
have used it a lot with all memory and limited by the boot option mem.
And I use it with zram. It has never frozen for me. It is the host
system for KVM, where I make the first tests of new daily builds.

2. Working systems without zRAM

When I run the current kernels of the daily builds and switch off zram,
the system will not freeze. I can make it slow with heavy swapping, I
can close programs and release data from the swap partition etc. Without
zram these systems have not frozen for me. I made and uploaded a tarball
of Saucybeta2. That system turns off zram automatically and can be used
to test other features without the zram freezing problem.

Best regards
Nio
