Thanks dmiller309 but your solution doesn't work for me. I don't think this bug is about GPU over temperature problem, it seems more due to bad temperature reading that lead to critical shutdown.
I was expecting to have details on what went wrong within system logs when critical shutdown occurs but the only related error is: [ 14.623699] k8temp 0000:00:18.3: Temperature readouts might be wrong - check erratum #141 There is no evidence of who causes the shutdown. I saw that there is AMD K8 (my and other bug subscribers configuration) problem reported here: http://lm-sensors.org/wiki/Devices -- laptop overheats and suddenly shuts down/off https://bugs.launchpad.net/bugs/370173 You received this bug notification because you are a member of Registry Administrators, which is the registrant for acpi. _______________________________________________ Mailing list: https://launchpad.net/~registry Post to : [email protected] Unsubscribe : https://launchpad.net/~registry More help : https://help.launchpad.net/ListHelp
