Machine randomly shutdowns down, twice

[Paul Sladen]

In the last 10 minutes, I've twice had the machine shutdown by itself.

My hunch is corrupt ACPI data leading to a zero-juice situation (both batteries are full charged *and* external power are available), combined with the lack of being able to pick a "Doing Nothing" option in GNOME Power Manager as a work around.

I had a shutdown again today; this one was a temperature threshold going critical:

  $ grep -A1 'shut.*down' /var/log/syslog
  Oct 6 10:43:47 localhost kernel: [26394.422223] Critical temperature reached (128 C), shutting down.
  Oct 6 10:43:47 localhost kernel: Kernel logging (proc) stopped.

Post reboot, temperatures of 73°C are showing:

  $ grep -r . /sys/devices/virtual/hwmon/hwmon*/temp*
  /sys/devices/virtual/hwmon/hwmon0/temp1_crit:127000
  /sys/devices/virtual/hwmon/hwmon0/temp1_input:73000
  /sys/devices/virtual/hwmon/hwmon0/temp2_crit:100000
  /sys/devices/virtual/hwmon/hwmon0/temp2_input:73000

Seems looking back at the log files from yesterday that the same probably happened.

  $ grep -A1 'shut.*down' /var/log/syslog.1
  Oct 5 12:03:34 localhost kernel: [55640.427116] Critical temperature reached (128 C), shutting down.
  Oct 5 12:03:35 localhost kernel: Kernel logging (proc) stopped.
