Title:
  Random "Watchdog detected hard lockup" when resuming from suspend

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Hi,

  I encounter a random bug when suspending my computer : everything suspends properly when I press the sleep button on the keyboard, but sometimes the computer freezes when I wake it up (by hitting the power button). So I have to power off the computer by long press on the power button, or reset the computer.
  I tried to suspend with the pm-suspend command, I got the same result.
  I tried to suspend through a TTY, and here I was able to get some logs (I took a photo of the log, attached to this bug report).
  The error message was the watchdog detected a hard lockup on the cpu (8 core cpu, so I got several times the message).
  The faulty software seems to be systemd-udevd, according to the trace I got. I googled a bit the problem, but wasn't able to very usefull information

  I wasn't able to find anything about the message I saw on the screen
  in the log files. No record at the time of the freeze. That really
  surprised me.

  I noticed also this problem related to suspend : I use virtualbox and
  if I suspend computer, resume it and try to launch a VM after, I can't
  get it running properly : it is very slow and I have to reboot the
  compter to get it working properly. And I noticed also if I have used
  a VM and after I suspend the computer, I am almost sure I'm gonna have
  a freeze when I wake the computer up. Maybe is there something related
  ?

  This problem happens randomly but I didn't find anything to reproduce it. 
  Here is the configuration of the computer : 
  -mother board : MSI h77ma-g43
  -cpu : intel core i7 ivy bridge series
  -ram : 16 gb
  -using onboard soundcard and video card
  -1 hdd 1.5 tb on sata 3
  -another 1 tb hdd on sata 3
  -bluray/dvd burner on sata

  Using Kubuntu 13.10 x64 everything up to date.

  Does anybody get the same or a similar problem ?
  If any more information is needed, please feel free to ask.
