I have already tried all boot options (acpi=force, acpi=off, acpi=osi_Linux, acpi_enforce_resources=lax) but without succes. > What kernel version do you use ? acpi thermal code has a bug since 3.13 which causes that kind of behavior. See https://bugzilla.kernel.org/show_bug.cgi?id=71711. This was only fixed last week. The emc driver won't help you to get this fixed, unfortunately. It only reports the temperature ... but you already know that it is too high.
