[Bug 1255610] Re: 100% CPU usage with "initctl emit plymouth-ready" process

[Garth Hitchens]

I have the same problem...  ps reports....
root      1093 64.7  4.2  78016 75796 ?        R     2013 23219:55 initctl emit plymouth-ready

After doing sudo cat /proc/$(pidof initctl)/stack > /tmp/initctl.stack,
I get...

garth at hat:~$ cat /tmp/initctl.stack 
[<c1637936>] work_resched+0x5/0x20
[<ffffffff>] 0xffffffff
garth at hat:~$ 

I was logged in via remote ssh so the kill -ABRT didn't allow me to
submit another bug...

Fully up-to-date Ubuntu 13.10.    Problem may have started during a
recent apt-get upgrade, Im' not sure.

  this makes my CPU very hot, I don't know how to debug deeper. Any
  ideas?
