** Description changed:

  Fresh install of 12.04 desktop. Updated 22 May with latest updates. The
  system mounts kerberized NFS4 shares with autofs5 from an ubuntu 10.04
  server. After a variable amount of time (minutes to a few hours) the
  system crashes with no shutdown possibility (neither local nor remote).
  Only option is a hard power-off.
  
  The system crashed 4 times in a single afternoon. Before configuring the
  NFS4 shares I did use the system for 2 days with no single crash. At the
  moment I disabled the mounts and for the moment the system is running
  OK.
+ 
+ WORKAROUND: Use Samba.
