Plamen, to clarify, you are using the default packages (not mainline
kernel) and everything is working?

Title:
  Ubuntu Freezes With No Obvious Reason

Status in linux package in Ubuntu:
  Fix Released

Bug description:
  I am dev and I know how this sounds but at a certain periods ubuntu
  freezes entirely. The only exit is the power button. I dont know what
  could be helpful information in this case so I will write everything I
  noticed so far (sry for the spam).

  This used to happen a lot while building with Android Studio but
  lately it freezes even when the studio is closed. The last time it
  happened after I closed(or tried to) Chrome tab while updating ubuntu.
  This behavior started a few weeks ago. I haven't updated to 15.10 at
  the time so I did. But it still continued to block. I thought it might
  be from the video driver so I switched from nvidia-340 to nouveau with
  no success.

  I cant find anything helpful in kern.log if its needed I can attach
  the log just before the freeze. What I find strange is in the syslog.
  At the time of the freeze it is filled with NULs. See attached image
  syslog.png. The time of the freeze was around 8:57. At this point the
  mouse cursor was active but there was nothing that reacted to my
  desperate clicks or keyboard shortcuts. After awhile the mouse stops
  as well and there is nothing I can do but the power button.

  Is there some other log that could be helpful or anything else I can
  do?

  
  Thank you in advance
