Public bug reported:
For the Lenovo L15 (with Ubuntu 20.04 and Kernel 5.10.0-1038.40) the F1,
F4 and NumLock LEDs remain lit after shutdown.
Boot of the machine via the power button is not possible until the battery is
drained and the machine is plugged via power chord. Alternatively, a hard reset
by pressing the Power-Button for 30 seconds allows for booting again.
In case of reboot instead of shutdown, the LEDs also remain lit for some
second, but reboot is done without problems.
The problem started after install of package "linux-image-oem-20.04b:amd
(5.10.0.1038.40, automatic)" and also persist after update to
5.10.0.1044.46.
Using to the generic kernel 5.11.0.27 does not show the same behavior.
