Hi Leann,

Actually, now that I have discovered what is going on, I don't think my
problem is a linux/ubuntu bug. It is caused by a broken acpi DSDT on my
computer. (I even paid to upgrade my bios before finding that article,
and it made no difference). It seems that a broken DSDT is not at all
uncommon.

A quick search of "cpu temp" in ubuntu bugs finds a few items which may
well be realted (85984, 111576, 27233, 152988) and also for "cpu fan"
(72775,64691,70599,140468,160291). (#140468 was exactly the problem I
was having in edgy.)

For the original problem reported for this bug, it is probably worth
looking at a the ACPI settings/logs including what temp it thinks the
CPU is and what the trip points, polling frequencies and initial fan
settings are. Every single one of those items (reported  temps, trip
points, polling freq, initial fan state) was broken for the DSDT on my
computer. Last night after fixing my DSDT and running a CPU intensive
task I got the CPU temp up to 50C (active cooling) and I heard the fan
speed up for a little while. After that it wouldn't get any hotter,
which I suppose is exactly what it is supposed to do.

So unless you think otherwise, I don't think there is any new bug to
report.

Cheers,
Randall.
