At shutdown I often get the message
watchdog did not stop!
and then the laptop freezes after few other lines without shutting down.
Any idea on how to fix this? Recently it happened very often, usually when the laptop was powered on for some time.
I am using Debian 8 on an Asus UX32LA
I found this systemd file (it shows a conflict with the shutdown.target), if it may help. My impression is that the problem depends on some issue coming from me trying to fix the backlight (which actually only works with the grub paramenter "acpi_osi=" )
