Running an Ubuntu Raring VM which was built a week ago that is now 
running 3.8-rc6, I was booting it last night when it hung.  After a few 
forced reboots, it came back up and I found the attached in kern.log.

Mostly, the VM has been used for testing anisble deployment, so not a 
lot of work, just upgrading and installing software, then rebooting.

Are these reports useful?  Is there any additional information I can 
provide from the VM?  What happens if it gets hung again, is there 
additional information I can gather?
