I STRONGLY suggest that this is NOT a duplicate of bug #1215513, as a
fix was distributed that fixes the "System Locks Up" part, but leaves
this error message.
In my first comment, both on this Bug and on Bug #1215513, I responded
to the error message by entering "fdisk /dev/ram0", under root, followed
by "p", which showed it to never be partitioned, or anything (like a
SWAP partition being defined). So it LOOKS like I was never in danger of
bug #1215513, but only experiencing the messages, noted in this Bug
(#1217189). Even though no "actual harm" is done, through a "pure
experience" of Bug # 1217189, the error messages still appear, after
"fix" of #1215513, which can CERTAINLY alarm production Linux
administrators anywhere, and cause loss of money in any case where the
Server is anything but something assisting non-profit volunteer work,
where they can be told they need to be patient and wait for their
services. (Actually, due to an early message by dac922, I was able to
disable zram services on a system that has no intention of using them).
Obviously, what happened was that the Kernel 3.8 work, IMPLEMENTING
zram0 swap was "back-ported" to the 3.2 Kernel tree, somewhere <=
vmlinuz-3.2.0-53-generic-pae!!! :-O
Remember, my system is Ubuntu 12.0.4 LTS Server, which, in my opinion is
not in any condition for "stray zram swap" creation! Fortunately,
somebody ported the package zram-config to 12.0.4, allowing me to get
it, which, in effect PERMANENTLY DISABLES the zram0 processes, because
they fail, during the install of zram-config, allowing "apt-get upgrade"
to state that it was not successful in the "install" of this package.
So I suggest that somebody on this forum, in either of these Bug reports
(again, I'm too busy administering Linux to normally submit fixes!) put
some of this text in some "FAQ file" somewhere,
Forgive my dry humor in this post. As a Linux admin, I'm trained to
"roll with the punches" and to consider the humor of life on Planet
Earth (and, forgive me for adding) the political system in the USA!!!
