applesmc not loaded at startup [gutsy,hardy,intrepid]

I also have a MacBook Pro 15" Core2Duo (mine is from november 2006, I'm not sure about yours).

applesmc is loaded automagically at startup (which is great).
The laptop is also very hot sometimes, it comes from the ATI GPU (Radeon X1600 Mobility), which oddly doesn't support powersaving under Linux. At the moment, there is nothing we can do about that. ATI/AMD is aware of the situation and does nothing (see http://www.phoronix.com/forums/showthread.php?t=3130 for the semi-official explanation).

After your upgrade from feisty to gutsy, have you also updated your linux kernel image to 2.6.22 ? (the package is linux-image-2.6.22-*). I remember I had to do it manually in my case. This new version contains many fixes to applesmc.

Regards,

I'm here at Macbook pro 15" C2D
applesmc doesn't get loaded by default, i have to do it by hand
otherwhise pommed and other things don't work correctly

the kernel version is 2.6.22-9
i am up to date with gutsy repository and still applesmc is not loaded at startup.

Hi, thanks for reporting this. Could you please provide the information requested on https://wiki.ubuntu.com/KernelTeamBugPolicies and https://wiki.ubuntu.com/DebuggingACPI ?

Since I have the same problem, here are the requested debug logs.... BTW

I'm confused ...
Looks like applesmc is loaded at startup because I added it to /etc/modules. I guess I did it right after my Gutsy install and totally forgot afterwards... ><

So the temporary workaround is : "echo applesmc >> /etc/modules"

Really sorry for all inconvenience

Confirmed, when I comment out applesmc from /etc/modules, it is *not* loaded on startup as expected. As such, I needed to load it manually and restart the pommed service to get things like the keyboard backlight working again.

I am assigning this bug to the 'ubuntu-kernel-team' per their bug policy. For future reference you can learn more about their bug policy at https://wiki.ubuntu.com/KernelTeamBugPolicies .

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

I think this is still an issue and maybe related to bug #262550.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

This was committed to kernel 2.6.28:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=dc924efb52ba9e4dffec5b15ae2242b894198139
and therefore is fixed in jaunty.
