Alex, this problem could be very machine specific and may be unrelated to the other reports. Please first make sure you are running the latest available BIOS and make sure your fans' performance match the needs of your CPU and are clean and not filled up with dust.
Would you mind opening a separate bug at bugzilla.kernel.org against the ACPI component. Please post /proc/acpi/thermal_zone/trip_points and acpidump there. Also do a: cat /proc/acpi/events (you need to kill other applications accessing /proc/acpi/events first -> fuser). Do you see (thermal or CPU related) acpi events when trip points are exceeded or if it gets hot? Does it work if you have only 1 process producing load? (E.g. if you compile a kernel with make -j6 it shuts down, but it works with just make?) There is an issue since some kernel versions, that it can happen, that an acpi event is not processed/ scheduled quickly enough to lower the frequency. -- CPU overheats during high usage "throttling <not supported>" https://bugs.launchpad.net/bugs/22336 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
