[Bug 56785] ACPI: No support for device type: thermal

[Henk Koster]

Public bug reported:

Binary package hint: linux-source-2.6.15

I'm running Ubuntu on Apple MacBook (Core Duo T2300 processor): Dapper
installed to the HD (kernel 2.6.15-26-686), or Edgy Knot-1 liveCD
(kernel 2.6.17). In both cases, ACPI does not activate the "thermal
zone", the /proc/acpi/thermal_zone directory is empty, so that the
command "acpi -V" gives the above error message.

Yet, temperature for the processor is available when running the MacBook
with OS X.

It is possible that the absence of temperature info under the Ubuntu
kernels is related to the fact that the MacBook runs decidedly hotter
(by feel) under Linux than under OS X, although precise figures are
difficult to fathom without thermal_zone info.

The Core Duo T2300 is not some niche processor, so I believe that the
Linux kernel should provide ACPI thermal_zone info with some urgency.
