Viktor Pal, thank you for reporting this and helping make Ubuntu better.
As per
http://h20564.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=5387476&swLangOid=8&swEnvOid=4060
an update to your computer's buggy and outdated BIOS is available
(2.65). If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

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, and the
information above is provided, then please mark this report Status
Confirmed. Otherwise, please mark this as Invalid.

Thank you for your understanding.

Title:
  kswapd kills the whole OS by eaing up resources

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I experience that my desktop (Ubuntu 15.04) gets unresponsive maybe once a week.
  When this happens the whole machine gets unresponsive immediately and only restarting helps.
  It only turns out from the atop logs what happened after the machine was restarted. Atop is configured to run every 30 secs.
  It is visible from the atop logs that kswapd0 is eating up all the CPU resources.
  Strange thing is that this happens despite there is no swap enabled.

  This happens mostly when Virtualbox is running and only a few amount
  of memory is available.
