[solved] new CPU, lmsensors stopped working (seemingly)

I bought a new CPU:

model name      : Intel(R) Pentium(R)  CPU       E6500  @ 2.93GHz
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 lm constant_tsc arch_perfmon pebs bts aperfmperf pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm xsave lahf_lm tpr_shadow vnmi flexpriority

This is what I get when I execute sensors:

coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +38.0°C  (high = +76.0°C, crit = +100.0°C)

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +36.0°C  (high = +76.0°C, crit = +100.0°C)
...

My problem is, that the two values (+38.0°C and +36.0°C) never change. They obviously changed with the previous CPU I had, depending on the load.
Rerunning sensors-detect didnt help.
I have tried the suggestion from the wiki (acpi_enforce_resources=lax), it didnt help.
Any help appreciated.

This problem is still not solved. Anyone any idea please?

Re: [solved] new CPU, lmsensors stopped working (seemingly)

first, check the bios (it probably has temps) and make sure the sensors are working - I've had a few broken ones - you can probably return the CPU and get a new one if that's the case, assuming you bought it from a retailer

if that's not the problem, maybe you need a special kernel module loaded and sensors-detect doesn't find it, but since you're getting temps I don't think it's likely (also be sure that sensors is in DAEMONS so that the detected modules are being loaded)

It may be a problem with lm_sensors itself. According to [Phoronix] LM_Sensors Finally Gets Better Intel CPU Support there are some patches for newer hardware. You could try to apply them yourself or wait for new lm_sensors release.

Re: [solved] new CPU, lmsensors stopped working (seemingly)

Guys, thanks for the advices. Why have I not thought of the bios, sigh. Of course the bios shows the same temperature as lm_sensors, so the problem is definitely the CPU (or it is incompatible with the motherboard maybe?). Also a problem with the new cpu is that when I start Virtualbox or KVM with accelerated virtualization, the whole system hangs sometimes. So I guess, it is time to bring it back to the shop.
Thanks again for your help.

Just for the record, the 4CoreDual-SATA2 motherboard was not compatible with INTEL Dual Core E6500 2,93GHz 775 BOX CPU, thus the problem. The interesting part is, that it worked well apart from the above mentioned problems.
