Problem with ACPI on reboot

cpi=off" option to kernel and the reboot problem disappear, but this time it's the shutdown process which is impacted. When I type shutdown the system succesfully halt but the MB doesn't physically poweroff Can anyone already had a similar problem ? Thanks Pierre GINDRAUD Informatic french student pgindr...@gmail.com

Re: Problem with ACPI on reboot

Thanks for your experience What do you mean by 'creating a msdos partition' ? Do you advice me to use the msdos partition table on the system disk and use a separated /boot partition for grub installer ? Pierre GINDRAUD Étudiant en école d'ingénieur année 2014-2017 Appre
