I started getting these about a week ago (Jul 2015)

They now happen several times a day in bursts (at the same second, same
error, but multiple process or thread ids)

I'm on 14.04.2 LTS

Here are some examples from syslog:

Title:
  SIGILL: chromium-browse[12042] trap invalid opcode ip:7f4e637e1c7d
  sp:7fff4a10d878 error:0 in chromium-browser

Status in chromium-browser package in Ubuntu:
  Confirmed

Bug description:
  Steps to reproduce:
  1. $ chromium-browser --temp-profile # just to rule out custom configuration
  2. Go to youtube.com/html5, opt in to html5
  3. Go to http://www.youtube.com/watch_popup?v=-JryxdydOj0&vq=480

  What happens:
  The tab goes Aw, Snap! and dmesg says "chromium-browse[12042] trap invalid opcode ip:7f4e637e1c7d sp:7fff4a10d878 error:0 in chromium-browser".

  What I expect to happen:
  I haven't bothered to check how it should behave, but at least it shouldn't crash.

  Additional information:
  Seems to happen with both chromium-codecs-ffmpeg and chromium-codecs-ffmpeg-extra (from Medibuntu) alike.

  I'm attaching a backtrace. I did my best with it, but I'll readily
  admit I have no idea of its value. Please do advise me if I more -dbg
  packages or something else is needed.
