Hi Joseph,

Testing the ISO file of post #22:

When zram is running in Lubuntu I can see zram block devices with
swapon -s
but I can see no such devices running from this ISO file.

- Is zram running although I see no zram block devices?
- How can I activate zRAM or check that it is really running?
- Or is this 'only' a test how the installation works with the new kernel and zram switched off?

See the following lists with commands and output.

Best regards
Nio

Title:
  Unexpected freezes Saucy

Status in “linux” package in Ubuntu:
  In Progress

Bug description:
  When using desktop-installer with lubuntu there is a freeze at the
  very end (bug 1225429) which also affects desktop-i386 and desktop-
  amd64. There are also unexplained freezes on the system when using it.
  Further tracking down has found
  http://ubuntuforums.org/showthread.php?t=2162655&page=3 and earlier
  today this arrived..

  As for freezing we discovered that since kernel 3.10.6 zram is broken
  which causes freezes and was fixed only completely in 3.12rc1. We
  backported that fixes in Neptune's Kernel I am not sure if the ubuntu
  kernel devs did the same.

  The links we have also found are  https://lkml.org/lkml/2013/8/12/29
  and  https://lkml.org/lkml/2013/8/19/17

  Disabling zram prevents the freeze in desktop-i386

  My machine specification is http://phillw.net/hardware/aDU4RVzY
  although using the lower RAM (512Mb) has been achieved by KVM
  http://phillw.net/hardware/LuFdGuxP increasing the available RAM to
  1GB does not show this error. It has also now been tested on 'real'
  hardware with 512Mb of RAM and is also showing the freeze (as well as
  with VBox).
