Subject: LKRG complains about battery being automatically unload
This happened in a VirtualBox VM. Just saw this once.
Jan 11 20:44:21 host kernel: battery: ACPI: Battery Slot [BAT0] (battery
present)
Jan 11 20:44:21 host kernel: [p_lkrg] ALERT !!! FOUND LESS[1] MODULES IN
DB IN MODULE LIST[54] THAN IN CURRENT MODULE LIST[55]

Jan 11 20:44:21 host kernel: [p_lkrg] ** EXTRA MODULE IS THE SAME AS

Not reproducible. Could be a race condition depending on when LKRG gets
load.
No idea why first the battery module was load and then automatically
unload. I remember your LKRG speech (youtube video) where you mentioned
"has to happen through kernel API". I guess if the battery module
automatically unloads itself or something else uses `rmmod battery` then
LKRG shouldn't even complain about this?
Another task perhaps for /etc/modprobe.d/30_lkrg.conf configuration file?

Might be related / same as my earlier message:
Possible to load LKRG through systemd-modules-load.service /
/usr/lib/modules-load.d / /etc/modprobe.d as last module? -
https://www.openwall.com/lists/lkrg-users/2020/01/11/1
Does this mean it's better to load LKRG through a systemd unit file
rather than systemd-modules-load.service?
Kind regards,
Patrick
