# uname -r 3.6.0-rc5-u1-smp+
I built a new 3.6-rc5 kernel (3.6.0-rc5-u2) using 3.6.0-rc5-u1 with 8 cores and power off didn't ocur. slipstream:/usr/src/linux-3.6.0-rc5-u1 # grep POWER .config # CONFIG_ACPI_PROCFS_POWER is not set # CONFIG_CPU_FREQ_DEFAULT_GOV_POWERSAVE is not set CONFIG_CPU_FREQ_GOV_POWERSAVE=m CONFIG_X86_POWERNOW_K8=m # CONFIG_PCIEASPM_POWERSAVE is not set CONFIG_INPUT_POWERMATE=m CONFIG_IPMI_POWEROFF=m CONFIG_POWER_SUPPLY=y # CONFIG_POWER_SUPPLY_DEBUG is not set CONFIG_PDA_POWER=m CONFIG_TEST_POWER=m CONFIG_POWER_AVS=y CONFIG_SENSORS_FAM15H_POWER=m CONFIG_SENSORS_ACPI_POWER=m CONFIG_SND_AC97_POWER_SAVE=y CONFIG_SND_AC97_POWER_SAVE_DEFAULT=0 # CONFIG_SND_HDA_POWER_SAVE is not set # CONFIG_HID_LCPOWER is not set CONFIG_DEVFREQ_GOV_POWERSAVE=y CONFIG_EVENT_POWER_TRACING_DEPRECATED=y # CONFIG_XZ_DEC_POWERPC is not set
When it was powering off "CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y" was set. slipstream:/usr/src/linux-3.6.0-rc5-u1 # grep PERFORMANCE .config # CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set CONFIG_CPU_FREQ_GOV_PERFORMANCE=y CONFIG_PCIEASPM_PERFORMANCE=y CONFIG_DEVFREQ_GOV_PERFORMANCE=y
slipstream:/usr/src/linux-3.6.0-rc5-u1 # grep MCE .config CONFIG_X86_MCE=y # CONFIG_X86_MCE_INTEL is not set CONFIG_X86_MCE_AMD=y CONFIG_X86_MCE_THRESHOLD=y # CONFIG_X86_MCE_INJECT is not set CONFIG_EDAC_DECODE_MCE=y # CONFIG_EDAC_MCE_INJ is not set
During the build temperature and power was around these values ------------------------------------------------------------------------------------- fam15h_power-pci-00c4 Adapter: PCI adapter power1: 133.30 W (crit = 124.77 W)
k10temp-pci-00c3 Adapter: PCI adapter temp1: +61.9°C (high = +70.0°C) (crit = +90.0°C, hyst = +87.0°C)
Immediately after the build the values are much lower than what it was with the kernel and config that caused the power off. ---------------------------------------- fam15h_power-pci-00c4 Adapter: PCI adapter power1: 31.10 W (crit = 124.77 W)
k10temp-pci-00c3 Adapter: PCI adapter temp1: +33.2°C (high = +70.0°C) (crit = +90.0°C, hyst = +87.0°C) ------------------------------------------
If needed I can go back to the earlier 3.6.0-rc5 kernel and config to recreate the power off situation. With the kernel that powered off, MCE was not set and CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
For the 3.6.0-rc5-u1 kernel only those 2 were changed. Regards Sid.
