Package: src:linux Version: 4.18.10-2 Severity: normal Tags: upstream (I am Cc'in the maintainers of the dell-laptop module, accordingly to modinfo.) After running this for about 1H: while true; do echo 1 > /sys/devices/platform/dell-laptop/leds/dell::kbd_backlight/brightness sleep 0.25 echo 0 > /sys/devices/platform/dell-laptop/leds/dell::kbd_backlight/brightness sleep 0.25 done most of the memory on my system is used and I get a flood of errors like these. This is a regression, I have noticed this behaviour for at least the past 4 months.
