Bug#869658: linux: system freezes when dell-smm-hwmon reads fan speed

The problem I do not think is in the bios,
I run the HWinfo32 software on windows 7 and the fan value is read continuously and correctly (in attachment)

In Debian, I would also like to point out that three fans are detected:

Fan Processor:
fan2:
fan3:

While my Dell Studio 1537 notebook has a single fan belonging to the component that
manages the heat dissipation of the processor and the video card.
Heatsink component: DP/N 0M139C

I also noticed that sometimes sensors show too much value for the value
fan3: 40981 RPM

dell_smm-virtual-0
Adapter: Virtual device
Processor Fan: 2837 RPM
fan2:          2833 RPM
fan3:          40981 RPM
CPU:            +41.0°C
CPU:            +52.0°C
Other:          +49.0°C
GPU:            +57.0°C

I would also like to know what temperature should I consider ?:

dell_smm-virtual-0
acpitz-virtual-0
coretemp-isa-0000

I hope this bug of the "dell_smm_hwmon" module can be solved,
I would not give up reading the correct temperature and fan values.
