[Bug 1432492] Re: Firefox and Thunderbird freezes entire system after a few seconds of use

[Gizmo Chicken]

Hi Dave,

I uploaded some screen captures that paint a better picture of what's
going on.  Please see the attachments to my above comments.

You suggested that I attempt to ssh into the frozen VM and, if possible,
look at relevant logs.  I was able to access my VM when its desktop was
frozen, but honestly, I don't know what logs I should be looking for.
I did, however, run "top" and noticed that one root process was at over
100% cpu usage while the desktop was frozen.  Please see "top.png"
attached  to Comment #19.

With regard to the QEMU logs on my host, I found nothing noteworthy.

I'm just a hobbyist, and tracking down bugs is a bit beyond my skill
level.  With that in mind, I hope maybe you or someone else who is more
capable than me would be willing to create an Ubuntu 15.04 VM and look a
little further into this.  Who knows, maybe this is just a quirk of my
system.  But if someone else can reproduce what I'm seeing, then this is
probably a pretty big issue, even if not always noticeable.

Regards,
GizmoChicken
