Hi to all,
About this email subject, on acer Aspire 5634WLMi machine and
9.1-RELEASE OS, FreeBSD shutdown the machine automatically in few
minuts.
In freebsd-es a similar problem was reported some months ago. The cause is
fan switch off after startup menu and rising temperature. It looks like ec
controller problem (Acer doesn't provide documentation about Embedded
Controller, all is done by try and error and can damage the laptop)
Yes, is the same situation.
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
41 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.
Thanks, see you.
