** Description changed:

  I'm not sure if this is actually a pm-utils or a kernel bug.
  So what happens is that after I hibernate my Laptop it does not recover in 
about 50% of the cases.
  During the recovery it simply unexpectedly restarts. Of course during this 
restart it does not enter the recovery phase again.
  This is the laptop model:

  The last entries from syslog (the entries before the entries of normal start):

  This belongs to the hibernation. So the recovery does not generate
  entries in syslog during the recovery.
  
  That's really annoying. I can't rely on hibernation although I really would 
need it.
  I bought this laptop because it is Ubuntu certified :)
  I see this on the above mentioned page: Hibernate is disabled on this system
  But does it mean that it will never be supported on this system?
  
  Could someone help me in how to debug this to be able to gather more 
information?
  If it's something I can correct I'm willing to do this., at least try.
  
+ I have used this documentation to debug this:
+ http://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt
+ 
+ The test hangs when running it with this setting:
+ echo processors > /sys/power/pm_test
