Public bug reported:

Hi there,

I'm getting this tpe of lines with dmesg:

[  274.924000] applesmc: wait status failed: c != 8
[  328.416000] applesmc: wait status failed: c != 8
[  378.072000] applesmc: wait status failed: c != 8
[  408.960000] applesmc: wait status failed: c != 8
[  459.000000] applesmc: wait status failed: c != 8
[  648.496000] applesmc: wait status failed: c != 8
[  821.572000] applesmc: wait status failed: c != 8
[  834.412000] applesmc: wait status failed: c != 8
[etc etc]

This is on a MacBook Pro with Kubuntu Feisty updated in 01/03/07 with
2.6.20-13-generic kernel.

I've investigated a little bit and found that applesmc is a driver to
control some Intel Mac's stuff, as it says the description:

"This driver provides support for the Apple System Management Controller, which
provides an accelerometer (Apple Sudden Motion Sensor), light sensors,
temperature sensors, keyboard backlight control and fan control. Only
Intel-based Apple's computers are supported (MacBook Pro, MacBook, MacMini)."

The author of the driver is related to Mactel people and seem he has
already some patches for it since 19/03, you can find them here:
http://lwn.net/Articles/226624/ . I don't know if he has more patches
than those one posted there, btw, maybe we could contact him or
something.

Thanks.
