[Bug 379780] Re: High cpu usage after upgrade to 141-1.1

[Alexander Federlin]

** Description changed:

  Binary package hint: udev
  
  Before I upgraded the udev version of jaunty from 141-1 to 141-1.1, top
  reported about 2% total cpu usage when idle. After the update, it rarely
  drops below 35%. Though top lists udevd among the more cpu hungry
  processes, it is only listed with about 3%, while system (in line 3)
  almost never drops below 20%.
  
  I am using the amd64 version of Xubuntu 9.04 on a Acer Extensa 5230
  laptop with a 2 GHz Intel Celeron processor, and I have my root, home
  and swap partitions encrypted with luks. I did a fresh install and
  installed nothing but the software updates.
  
  The output of top looks like this:
  
  top - 18:47:33 up 15 min,  2 users,  load average: 1.48, 1.99, 1.50
