| |
I have a huge heatsink and large CPU fan plus lots of cooling fans in the case and nothing gets hot. If I build e.g 3.6-rc5 with 8 or 6 cores, part way through it suddenly powers off.
I have checked hwmon/k10temp.c to see if I could see where these values were defined.
k10temp.h is 0 bytes. -rw-r--r-- 1 root root 0 Sep 9 01:59 /usr/src/linux-3.6.0-rc5/include/config/sensors/k10temp.h
Currently I build with "make -j 1" and temperature and power values are around those below. # sensors k10temp-pci-00c3 Adapter: PCI adapter temp1: +60.4°C (high = +70.0°C) (crit = +90.0°C, hyst = +87.0°C)
fam15h_power-pci-00c4 Adapter: PCI adapter power1: 127.49 W (crit = 124.77 W)
# cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 21 model : 1 model name : AMD FX(tm)-8150 Eight-Core Processor stepping : 2 microcode : 0x6000626 cpu MHz : 3600.000 cache size : 2048 KB
from .config:- # grep HWMON .config CONFIG_IXGBE_HWMON=y CONFIG_HWMON=y CONFIG_HWMON_VID=m # CONFIG_HWMON_DEBUG_CHIP is not set CONFIG_THERMAL_HWMON=y
# grep POWERSAVE .config # CONFIG_CPU_FREQ_DEFAULT_GOV_POWERSAVE is not set CONFIG_CPU_FREQ_GOV_POWERSAVE=m # CONFIG_PCIEASPM_POWERSAVE is not set CONFIG_DEVFREQ_GOV_POWERSAVE=y
On another 6-core box I can build kernels with "make -j 6" without problems. # cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 21 model : 1 model name : AMD FX(tm)-6100 Six-Core Processor stepping : 2 microcode : 0x6000623 cpu MHz : 3300.000 cache size : 2048 KB
With a kernel build going on six core box, temperature and power hover around the values below. sabre:~ # sensors k10temp-pci-00c3 Adapter: PCI adapter temp1: +50.2°C (high = +70.0°C) (crit = +90.0°C, hyst = +87.0°C)
fam15h_power-pci-00c4 Adapter: PCI adapter power1: 94.40 W (crit = 95.01 W)
