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
