Uhh, sorry, it seems something got mixed up somewhere. As mentioned
earlier in this thread already: The Studio XPS 8000 I have here never
froze when loading or using dell-smm-hwmon. I only saw its CPU fan speed
going up and down as described in From the mail that
started this thread I got the impression that all those problems are all
related somehow, so I went testing the patch as asked.
