Comment 12 for bug 524956

Please note: this bug does not only effect thermal sensors. It effects almost all things that might require ACPI. For example, The keyboard WiFi / Bluetooth/Webcam on/off switches and lid detection buttons also do not work with current (Lucid Beta 1) kernel. I can confirm that reversing commit 6a63b06f3c494cc87eade97f081300bda60acec7 fixes all those issues on my System76 Pangolin (PanP5) when compiling the 2.6.32-9.13 kernel under Karmic. I have not tested the fix in Lucid, but I can't imagine it not working there as well.

There is a patch for this problem, but I have not been successful applying it to a 2.6.32 source tree. I believe the patch is for 2.6.33. Perhaps the best solution is to backport that patch to 2.6.32-* (see https://bugzilla.kernel.org/show_bug.cgi?id=14667#c89 ). It seems pretty clear that this bug effects more than just one or two laptop models and needs to be fixed before Lucid becomes final.
