Title:
  System freeze with long strings of NUL characters (^@) in the logs

Status in linux package in Ubuntu:
  New

Bug description:
  Experienced a system freeze. It was not possible to use the keyboard
  or the touchpad, it was possible to move the cursor using an USB mouse
  attached, but clicking had no effect. The strange thing is that at the
  time of the freeze /var/log/syslog and /var/log/kern.log displayed
  long strings of NUL bytes (^@).
