این رو تیو یک فروم دیدم احتمالا درست جواب بده .
It sounds likely, as you indicated, that your actual problem is related to changing ACPI settings. The answers on this Debian forum thread suggest the following:
Edit the file at /etc/default/grub and edit the GRUB_CMDLINE_LINUX line to look like this: GRUB_CMDLINE_LINUX="reboot=bios"
Run update-grub. If reboot=bios doesn't work, they suggest retrying with reboot=acpi
reboot=bios worked for me.
