I force a crash at around 03:25. Seconds before the provoked crash, all was running well, including networking. I will try a wired connection another time.
Here is some output of /var/log/messages: Feb 2 01:45:38 golarina -- MARK -- Feb 2 02:05:38 golarina -- MARK -- Feb 2 02:25:39 golarina -- MARK -- Feb 2 02:45:39 golarina -- MARK -- Feb 2 03:05:39 golarina -- MARK -- Feb 2 03:25:19 golarina syslogd 1.4.1#18ubuntu6: restart.
