Arne Henningsen, as per http://h20564.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=5071172&swLangOid=8&swEnvOid=4158 an update to your computer's buggy and outdated BIOS is available (F.50). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-f.50 ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1540013 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.
