The code implies the "CPU TDP doesn't match expected value" is a sanity check failing. Should that happen, or is there something wrong? /proc/cpuinfo for the first core: processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 37 model name : Intel(R) Core(TM) i3 CPU M 330 @ 2.13GHz stepping : 2 cpu MHz : 933.000 cache size : 3072 KB physical id : 0 siblings : 4 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 11 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx rdtscp lm constant_tsc arch_perfmon pebs bts rep_good xtopology nonstop_tsc aperfmperf pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm sse4_1 sse4_2 popcnt lahf_lm arat tpr_shadow vnmi flexpriority ept vpid bogomips : 4256.29 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: /sys/devices/virtual/dmi/id/: bios_date: 06/21/2010 bios_vendor: Dell Inc. bios_version: A05 board_asset_tag: board_name: 07NTDG board_vendor: Dell Inc. board_version: A05 chassis_asset_tag: chassis_type: 8 chassis_vendor: Dell Inc. chassis_version: A05 product_name: Inspiron N4010 product_version: A05 sys_vendor: Dell Inc. -- Cesar Eduardo Barros cesarb@cesarb.net cesar.barros@gmail.com
