[Bug 1348852] [NEW] CPU being maxed out 14.04 Trusty Tahr

[Corey Hollaway]

Public bug reported:

With a fresh Xubuntu 14.04 LiveUSB I did (most of this doesn't matter):

sudo apt-get update
sudo apt-get install firefox
sudo stop cups
sudo stop cups-browsed
sudo dpkg --purge hplip printer-driver-postscript-hp printer-driver-gutenprint bluez-cups printer-driver-hpcups cups cups-browsed cups-daemon printer-driver-splix cups-core-drivers
sudo add-apt-repository ppa:ubuntu-wine/ppa
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install wine1.7

And now, I get this (with `ps aux`):
http://paste.ubuntu.com/7860430/

Something just recently broke plymouth because earlier today I did the
same thing and my CPU didn't max out.

Firefox didn't break things because I had 31.x before and everything was
fine.

I look at my CPU graph analyzer GUI on my Xubuntu panel and plymouth-
upstart-bridge seems to select 2 random CPU cores (I have 4. An Intel
i3) and maxes them out. Every ~10 seconds it changes to two random
cores. *shrugs*
