Hi Rafael, Mario,
Stephen is having an issue with a recent AMD laptop (a Lenovo Ideapad model)
where Linux defaults to using S3/deep suspend instead of S0ix/s2idle.
This is causing the sensors provided by the AMD Sensor Fusion Hub
to stop working after a suspend/resume. Adding mem_sleep_default=s2idle
to the kernel commandline fixes this.
Do you have any idea what might be causing this ?
Regards,
Hans
