The most important ones would be tagged MCE (Machine Check Exception). If the ACPI trips over a thermal threshold, you get a "Critical threshold" event followed by a shutdown.
If MCE notices that the CPU package (CPU+GPU) is too warm, you get ""CPU[01234]: (core|package) temperature above threshold, cpu clock throttled", and a message when the chip is cool enough again. They will be visible in dmesg, and should be logged in /var/log/messages -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1137817 Title: [ivb] System freeze after high memory usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1137817/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
