[ 61.689778] intel ips 0000:00:1f.6: CPU TDP doesn't match expected value (found 25, expected 29) [ 61.689805] intel ips 0000:00:1f.6: PCI INT C -> GSI 18 (level, low) -> IRQ 18 [ 61.690236] intel ips 0000:00:1f.6: IPS driver initialized, MCP temp limit 90 The ips-monitor thread runs continuously in D-state and produces therefore a continuously high load - even if the processor is "idle", the load is exactly 1. ps aux | grep ips root 593 0.0 0.0 0 0 ?

Expected Results: 18:38pm up 0:42, 5 users, load average: 0.01, 0.07, 0.10 -> Load should be 0 if the machine is idle. processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 37 model name : Intel(R) Core(TM) i5 CPU M 460 @ 2.53GHz stepping : 5 cpu MHz : 2533.000 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 nopl xtopology nonstop_tsc aperfmperf pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm sse4_1 sse4_2 popcnt lahf_lm arat dts tpr_shadow vnmi flexpriority ept vpid bogomips : 5053.43 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: (+ 3 more times) lspci -vv 00:00.0 Host bridge: Intel Corporation Core Processor DRAM Controller (rev 02) Subsystem: Micro-Star International Co., Ltd.
