I don't solved the problem. For this reason I post here now. And, I wait a long time for try new situations and not crossposting the problem in other mailing list. > > > How can I debug the reason of the problem ? > > A not so good wokaround is down the temperature where cpu Hz is adjusted: > > #sysctl hw.acpi.thermal.user_override=1 > #sysctl hw.acpi.thermal.tz0._PSV=65C > #sysctl hw.acpi.thermal.user_override=0 > First of all, I load the correct ACPI mapping driver for acer laptops ( this situation ): acpi_wmi(4) root@casa:/root # kldstat | grep acpi 4 1 0xc13dd000 462c acpi_wmi.ko root@casa:/root # Now I try yours values: First, de defaults values: root@casa:/root # sysctl -a | grep hw.acpi.thermal.user_override hw.acpi.thermal.user_override: 0 root@casa:/root # sysctl -a | grep hw.acpi.thermal.tz0._PSV hw.acpi.thermal.tz0._PSV: -1 root@casa:/root # sysctl -a | grep hw.acpi.thermal.tz1._PSV hw.acpi.thermal.tz1._PSV: 95,0C root@casa:/root # sysctl -a | grep hw.acpi.thermal.user_override hw.acpi.thermal.user_override: 0 root@casa:/root # I change to your suggerations: root@casa:/root # sysctl hw.acpi.thermal.user_override=1 hw.acpi.thermal.user_override: 0 -> 1 root@casa:/root # sysctl hw.acpi.thermal.tz0._PSV=65C hw.acpi.thermal.tz0._PSV: -1 -> 65,0C root@casa:/root # sysctl hw.acpi.thermal.tz1._PSV=65C hw.acpi.thermal.tz1._PSV: 95,0C -> 65,0C root@casa:/root # sysctl -a | grep hw.acpi.thermal.user_override hw.acpi.thermal.user_override: 1 root@casa:/root # sysctl -a | grep hw.acpi.thermal.tz0._PSV hw.acpi.thermal.tz0._PSV: 65,0C root@casa:/root # sysctl -a | grep hw.acpi.thermal.tz1._PSV hw.acpi.thermal.tz1._PSV: 65,0C root@casa:/root # I look for the temperature at the moment: root@casa:/root # sysctl -a | grep temperature acpi_tz1: temperature 67.0C: decreasing clock speed from 500 MHz to 250 MHz acpi_tz1: temperature 67.0C: decreasing clock speed from 250 MHz to 125 MHz hw.acpi.thermal.tz0.temperature: 73,0C hw.acpi.thermal.tz1.temperature: 72,0C dev.cpu.0.temperature: 75,0C dev.cpu.1.temperature: 75,0C root@casa:/root # I try compile one port ... : ... while compile I look the temperature: root@casa:/root # sysctl -a | grep temperature acpi_tz1: temperature 67.0C: decreasing clock speed from 500 MHz to 250 MHz acpi_tz1: temperature 67.0C: decreasing clock speed from 250 MHz to 125 MHz hw.acpi.thermal.tz0.temperature: 95,0C hw.acpi.thermal.tz1.temperature: 94,0C dev.cpu.0.temperature: 92,0C dev.cpu.1.temperature: 92,0C root@casa:/root # I break the compilation because if hw.acpi.thermal.tz%d.temperature ( of ACPI_THERMAL(4) ) = 100C the FreeBSD shutdown automacally. > Or downgrade to 8.x > On 8.x I get the same problem.
