Bug Description

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.

Let's get the dmesg for this system please. Attach it (do no paste it into comments).

Also do this please:

sudo cat /proc/acpi/dsdt > DSDT.aml

Attach that to this bug report as well.

Thanks

Can you test this on Edgy RC so we can see if this problems still exists?

I can't test this anymore because I've switched to running Ubuntu in a
Parallels VM running under OS X (and I'm well pleased with that).

I can confirm this is still an issue with Edgy RC:

This is still a bug in Edgy final.

I encounter the same problem onder Dapper Server and an Epia Via M10000 mobo. I cannot say if the problem is the same under Breezy.
My guess is that this problem is not limited to the Core Duo T2300 processor.

Ok, I tested with Feisty Herd 4.

I still don't have anything under /proc/acpi/thermal_zone

Would you like us to test anything specific?
(This is a Core 2 Duo, by the way)

Thanks,

The DSDT contains no thermal zones, so there's no way for ACPI to provide this information.

I have the same problem on my new motherboard (Pentium4-3ghz-HT) and kernel 2.6.15-28 on my dapper server. I have moved HDs from an AMD motherboard to this one and I have lost all acpi temperature monitoring.
Attaching here dmesg

Hi there.

I have the same problem on my desktop box with Asus P5K motherboard and Core2 Duo E4700 @2.60 GHz running on Hardy Heron, kernel 2.6.24-19-386 I can't get working CPU freq scaling and I can't even see the second CPU listed in my specs, or in the sensors section or somewhere else. This is very annoying and frustrating. Can anyone help me with this please? Output of dmesg and DSDT.aml attached. Thanks in advance.

I have the same problem on my desktop with Hardy running kernel 2.6.24-19-generic and acpid version 1.0.4-5ubuntu9. My motherboard is MSI K7T Turbo-R Limited Edition with 1.2GHz AMD Athlon CPU. (Motherboard: MS-6330, Award BIOS v.3.6). Hardy does not control fan speed either. However, lm-sensors can read BIOS information just fine:

$sensors
via686a-isa-6000
Adapter: ISA adapter
CPU core: +1.83 V (min = +0.06 V, max = +3.10 V)
+2.5V: +0.36 V (min = +0.06 V, max = +3.10 V)
I/O: +3.42 V (min = +3.12 V, max = +3.45 V)
+5V: +5.03 V (min = +4.73 V, max = +5.20 V)
+12V: +12.85 V (min = +11.35 V, max = +12.48 V)
CPU Fan: 5921 RPM (min = 0 RPM, div = 2)
P/S Fan: 0 RPM (min = 0 RPM, div = 8)
SYS Temp: +55.5°C (high = +146.2°C, hyst = -70.9°C)
CPU Temp: +42.4°C (high = +146.2°C, hyst = -70.9°C)
SBr Temp: +24.2°C (high = -70.9°C, hyst = -70.9°C)

The problem of Ubuntu not controlling the fan speed was there in Gutsy and now exists in Hardy.
