** Description changed: 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 (^@).
