I have an issue with hibernation on my Lenovo ThinkPad laptop (E531) that
runs the Debian testing stream. The default kernel is 4.19.0-4-amd64 and I
use the KDE Plasma desktop.
The laptop will hibernate once after a fresh start using the default
kernel. But the second time, it refuses to hibernate and I have to do a
With the other kernel available on the system - as you are all aware, apt
retains the latest two kernels for boot purposes - 4.19.0-2-amd64, the
