OK, so far I tried it, but it just doesn't work. I tried to get a crash
dump without success. I increased the crashkernel size to 256M, I
enabled additional panics but there's not way. My system just freezes
and nothing is possible again.

So, let's see:
* text console doesn't work
* photo: you would just see my frozen desktop, nothing more. There are not error messages
* linux-crashdump: I can't catch it. I installed linux-crashdump, changed crashkernel size from 128M to 256M because testing didn't work. Not it does and it creates a crash dump. But when my system freezes the way it occassionally does, it does not catch anything in the file. It also does not reboot. So what to do, if even this fails?
* kern.log I couldn't find anything interesting there. I added a truncated version 
* ssh: doesn't work
* netconsole: doesn't work either.

The ram should be fine. I tested it before, when I already had the
problems. Also: Windows 8 does not crash, so I guess it's a Linux issue.

Title:
  Ubuntu freezes occasionally

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I am running Ubuntu 15.10 and my notebook freezes occasionally. I had
  the same issue with Ubuntu 15.04, but I thought that 15.10 might
  change it. I am running Ubuntu on an Acer Aspire ES1-311 (P1D5).

  I have no clue what causes this, my system just freezes and I can't do
  anything anymore. ctrl+alt+f1 doesn't work as well as alt+print+REISUB
  doesn't work either. It's just frozen. I have to power down manually.

  Last time I was programming only with a gnome-terminal and atom
  (editor) opened. I checked some log files but I couldn't find anything
  suspicious.

  Any ideas?
