Yes, it reports a negative temperature. But this is reported by the
kernel. acpi only reads this information and displays it. The problem
doesn't seem to be in acpi, but in the kernel itself.
I did some more research regarding ACPI and found out that on both systems
there is a flawed ACPI DSDT.
Using acpidump I stored the DSDT into a file and disassembled it with iasl.
When comiling the file back into a binary file I get one warning and two
errors on both systems which look quite similar.

I found a suggestion how to fix the warning, but did not find anything for the

I do not understand a single word from it, so there is not a real chance to
fix it myself.
Some time ago I read about a DSDT fix that has been removed from the kernel,
but I do not know if this is related to the problem we see here.

please report bug upstream in bugzilla.kernel.org one shouldn't need to
fiddle with DSDT tables.
and please let us know the upstream bug number.

I don't really see the problem. You can have both kernels installed at the same time. Just install the 2.6.25 package, boot into this kernel once, test acpi, boot back into 2.6.24 and remove the 2.6.25 package again. Hello Michael, I have a second system available now which shows the same behaviour, it is also a Shuttle barebone, but it is brand new and still available for tests. I installed the OS which installed kernel 2.6.22 (lenny). The temperature is always reported to be 40 degrees C, absolutely independent from the circumstances (yesterday and today). I updated to kernel 2.6.24 (lenny). Nothing changed. Fan is on, temperature is 40 C. Then I updated to 2.6.25 (sid). And again: no change in temperature or fan state. After that I did some more research and found that value stored in the file /proc/acpi/thermal_zone/THRM/polling_frequency is always polling disabled. I guess this indicates that the values never gets updated. Neither the temperature nor the state of the fan. Asking Google I found some reports in blogs and fora (Debian forum and Ubuntu forum) reporting the same problem: Absolutely NO update of the temperature and wildly absurd values (everything from -270 C to over 80 C). Some reporters could fix the problem by manually changing the dsdt (reading the table into a file, disassembling it, changing the code, recompiling it and then copying it back into the original place). The temperature is reported correctly the and gets updated. And the fan is controlled accordingly. There should be a repository of dsdt files on http://www.lesswatts.org/projects/acpi/, but I could not access the site as the connection always times out. Here are the first bytes of my dsdt of the older system: 44 53 44 54 85 42 00 00 01 0b 58 50 43 20 20 20 |DSDT.BXPC | 0010 53 44 33 32 56 31 30 00 00 10 00 00 4d 53 46 54 |SD32V10.MSFT| The systems that have been reported to be affected have been from many major brands, so this seems to be more or less widespread.
