Actually there definitely are more problems in both hardware and kernel
space, so I basically have no choice other than relying on userspace.
This is probably off-topic for this bug report, but if you have an idea
I'd be glad to hear:

There seems to be a race condition in the linux kernel. Both the acpi
code and the sensors code access the same piece of hardware and by doing
so concurrently they sometimes manage to confuse it, which results among
other things in turning the cpu fan off. Of course either kernel group
would blame the other. Also linux seems to disable the feature turning
the computer off or at least change the limits to useless values. The
hardware device in question is driven by w83627ehf.

Uhh, sorry, I should have read more carefully. On my system the
formatting looks a bit different making this item much harder to spot.

Great.
