ams: Lots of kworker activity after wake from hibernate on Powerbook

[Mathieu Malaterre]

Dear all,

I am hoping someone could help me diagnose the following bug report:

https://bugs.debian.org/798102

[...]
After waking from hibernate, I get lots of kworker activity that makes my
fans kick in.  Top shows a process called kworker/0:3 always active using
around 3% cpu, and Powertop shows a process using 320 ms/s with the Category
Kwork and the Description ams_worker (Powertop also shows about 33% cpu usage).
I assume ams stands for Apple Motion Sensor, and when I unload the module
"ams" everything returns to normal and my fans quiet down.

This is on an aluminum Powerbook (PowerBook5,6).

Is there any tool to use to check the behavior of the ams kernel module ?

Thanks much
