Arne Henningsen, in order to allow additional upstream developers to examine
the issue, at your earliest convenience, could you please test the latest
upstream kernel available from
http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind
the following:
1) The one to test is at the very top line at the top of the page (not the
daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was
released upstream.
4) Install instructions are available at
https://wiki.ubuntu.com/Kernel/MainlineBuilds .
If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.
If the latest kernel did not allow you to test to the issue (ex. you couldn't
boot into the OS) please make a comment in your report about this, and continue
to test the next most recent kernel version until you can test to the issue.
Once you've tested the upstream kernel, please comment on which kernel version
specifically you tested. If this issue is fixed in the mainline kernel, please
add the following tags by clicking on the yellow circle with a black pencil
icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ
Where X, and Y are the first two numbers of the kernel version, and Z is
the release candidate number if it exists.
If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ
Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.
Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.
Thank you for your understanding.

Title:
Ubuntu gets slow and freezes, because 'invisible' processes use all
memory
Status in linux package in Ubuntu:
Incomplete
Bug description:
I usually suspend my computer (HP EliteBook 8560w) to RAM if I
tranport it or I don't need it and I restart it only once a month or
so. However, since a few weeks, my computer gets slow, sluggish, and
ultimately freezes after using it for some hours, because some
'invisible' processes use all the RAM (8 GB). When I notice in time
that there is no or little memory left in RAM so that the computer
starts to use swap memory and I immediately close all programs, I can
restart the computer before it gets unresponsive. I have to restart my
computer at least once per day (often by pressing the on/off button
for a long time, when I did not manage to restart the computer before
it became unresponsive). Although a lot of memory is used, the
processes that use most of the memory are not listed by "System
Activity" or "top" (I will attached a screen shot and a text file that
illustrate this). Hence, it seems that some 'invisible' processes use
nearly all of the memory.
I ran MemTest86 (from the boot menu) but it did not find any errors.
I did not use 'apport' to report this bug, because it does not really
work:
https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1539263
but I managed to save the information collected by apport, which I
will attach.
Which further information do you need?
