The closest thing I've seen to this is a system running systemd go to sleep during the boot process. From what I'm told there are some odd interactions that are possible between systemd and acpi scripts + event triggers. There's an interesting talk about methods of debugging systemd boot issues that happened at DebConf15 that might be helpful in debugging this: http://meetings-archive.debian.net/pub/debian-meetings/2015/debconf15/Your_systemd_tool_box_dissecting_and_debugging_boot_and_services.webm > Afterwards I was able to get it to boot > all the way into the Mate desktop, and used it for about 10 minutes one > time, about 30 min the next.

That's also quite possible; for obvious reasons you'll eventually want to figure out how to throttle the system rather than have it hit the temperature limit and cause a shutdown. -- Chris -- Chris Knadle [email protected] _______________________________________________ Mid-Hudson Valley Linux Users Group http://mhvlug.org https://mhvlug.org/cgi-bin/mailman/listinfo/mhvlug Upcoming Meetings (6pm - 8pm) Vassar College * Oct 7 - Understanding Systemd Nov 4 - Imposter Syndrome Dec 2 - Distributed Filesystems And Ceph
