Subject: AMD Bulldozer FX-8150 Powers off during kernel build
Date: Thu, 13 Sep 2012 02:30:27 +0100 [thread overview]
Message-ID: <50513733.8040801@blueyonder.co.uk> (raw)
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.

/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)
73 ... Sid.
