I finally found a way to bypass the
      grub installation that was hanging. Just did 
      pkill grub*
      
      Then I added 
      GRUB_DISABLE_OS_PROBER=true
      to /etc/default/grub
      and typed 
      update-grub
      
      The upgrade is now smooth and fast. 
      However, it still takes about 5 minutes to reboot with the same
      messages shown below.

      Thanks for the reply,
      
      I did a Jessie dist-upgrade but I have been on testing for
      sometimes so it was not such a huge upgrade. 
      
      On reboot (after trying to finish the installation of grub) I get
      
      INFO: task mount:12243 blocked for more than 120 seconds
      "ech0 0 > /proc/sys/kernel/hun_task_timeout_secs" disables this

      and then it reboots.
      
      For me upgrade problem, it comes from the update-grub, if I run it
      I can the same 
      Generating grub configuration file ...

      I will try to purge and reinstall grub. I have seen it as a
      solution for Ubuntu
