[Bug 1348852] Re: CPU being maxed out 14.04 Trusty Tahr

[Corey Hollaway]

It happened again. Except this time only one plymouth-upstart-bridge
process was hogging CPU. Which means only one core of my processor was
being used.


:(

this sucks.

** Summary changed:

- CPU being maxed out 14.04 Trusty Tahr
+ plymouth-upstart-bridge takes 100% CPU after upgrading packages in 14.04 Trusty Tahr

Title:
  plymouth-upstart-bridge takes 100% CPU after upgrading packages in
  14.04 Trusty Tahr

Status in “plymouth” package in Ubuntu:
  New

Bug description:
  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`):

  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*

  Laptop stats:

  i3 (1.9GHz)
  6 GB RAM
  integrated Intel HD 4000 graphics

  These are the packages that were updated:
