[SOLVED] MBP4,1/MBA 'wait status failed: c != 8' solved?
UPDATE 12DEC2011: Since FEB2011, most Macbook models should work out of the box, without patching the kernel. If you experience problems or suspect your machine is different somehow, please read on.
UPDATE 28APR2010: For the latest applesmc, see the applesmc-dkms package in the Mactel PPA: https://wiki.ubuntu.com/MactelSupportTeam/PPA
If you have a Mac that is yet unsupported by applesmc, please reply to this post, gathering the information below.
* Determine your exact mac model
Code:
sudo dmidecode -s system-product-name
* Run the applesmc-test.sh script (found below in this post) to get a picture of the performance before the patch
(you may need to do 'chmod +x ./applesmc-test.sh' before it runs)
* Run the scan-smc.sh script (found below in this post), and attach the output.
Code:
sudo ./scan-smc.sh > scan-smc-MODEL.txt
(you may need to do 'chmod +x ./scan-smc.sh' before it runs)
After some time, a reply with a new version of applesmc-dkms attached will appear. Then please run applesmc-test.sh again. Once satisfactory, the change will be incorporated in the Mactel PPA, and a patch sent upstream.
For more information, see http://bitmath.org/code/applesmc-dkms/

It might be helpful if there was a test app or something that could verify the functions. Do you know if there is one or maybe a procedure for testing with stuff that is available?

I did not fully understand what you mean here, but if you think of a script that checks the availability of accelerometer, backlight, leds, fans, temperatures etc, that could be quite handy. However, currently the testing is about whether this works at all for some machines, which is easily verified by the number of errors in dmesg from applesmc.

Thought so ;) I thought you'd like to see your work on phoronix.

Actually, I don't know of anything that uses the accelerometer... backlight should work with pommed, and the fan control files can be seen in the dev tree. You have a good point on the messages though.

EDIT 28APR2010: see first post in thread for current script versions [old version deleted].
On request, here is a small script that can be run to test the performance of applesmc on your computer. Simply run it in a terminal as a normal user. Cheers!

Binary for Intrepid running 2.6.27-3-generic on i386 available, see the first post.

Hi,
thanks for figuring out how to get basic support. The 'c != 8'-problem seems to be solved ;-), but there are other issues on a MacBookPro 4 (Penryn):
Code:
Sep 21 21:38:07 snoopy kernel: [12118.120999] applesmc: Apple MacBook Pro detected:

Sep 21 21:46:49 snoopy kernel: [12268.875983] applesmc: wait status failed: 5 != 4
while running your test script:
Code:
accelerometer: present, readable, output: (2,10,233)
fan: present, readable, output: 1000
light: present, readable, output: (15,44)
leds: present,
led: readable, output: 0
temperatures: present,
temperature: readable, output: 44750
temperature: readable, output: 35000
temperature: not readable
temperature: not readable
temperature: readable, output: 33750
temperature: readable, output: 51000
temperature: readable, output: 48500
temperature: readable, output: 50250
temperature: not readable
temperature: not readable
temperature: readable, output: 49750
temperature: readable, output: 42500
performance: reading all temperatures
fail frequency: 1.000
reads per second: 16
Probably due to errors reading non-existent temperature sensors (how many does this model have?).
But light sensors, keyboard backlight and fan speeds seems to work most of the time, although the GNOME applet sometimes complains about missing data/unreadable fan speeds.
ciao,
Mario

those temperature sensors not readable are: 1, 6, 7, 12 and the sensors command shows:
Code:
applesmc-isa-0300
Adapter: ISA adapter
Left side : 999 RPM (min = 1000 RPM)
Right side : 996 RPM (min = 1000 RPM)
temp2: +33.8°C
temp3: +51.2°C
temp4: +49.2°C
temp5: +51.2°C
temp8: +50.2°C
temp9: +42.5°C
temp10: +44.8°C
temp11: +35.0°C
