Since I've installed Debian 10 Buster on my laptop (2009 or so ASUS) I'm not able to shutdown or reboot my computer properly. I've re-installed the OS countless times with no success. I'm using LXDE as DE.
Whenever I press the shutdown or reboot buttom from the GUI or I use the terminal to type the dedicated commands my system hangs for more than twenty minutes on
Reached target Power-Off or
Reached target Reboot.
I've edited the grub configuration file removing the quiet boot option and I've found out the last thing systemd is trying to do is
Stopping disk when shutting down, or
Synchronizing SCSI cache when rebooting.
After reading this I tried both
poweroff -f and
reboot -f and none of them worked.
So is this a kernel related issue? I don't know how to proceed.
I've even saved my systemd shutdown log with debug options enabled.
