Title:
Suspend stopped working from 4.4.0-157 onwards
Status in linux package in Ubuntu:
Incomplete
Bug description:
Since upgrading the kernel above 4.4.0-154, starting with 4.4.0-157,
suspend does not work for me anymore. Never had such an issue in the
last 6 years.
This is the relevant output when suspend fails:
