ACPI: Core revision 20060707

I’ve installed Debian on an older Acer notebook recently; the installation was finished normally but then the system hanged during the boot with message: “ACPI: Core revision 20060707”.

The solution was to add acpi=off to the grub.

For permanent effect you can do the following:

# nano /etc/default/grub

Change line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"

# update-grub

Reboot.

Update:

Please note, disabling ACPI may lead to overheating of your computer.

The message might be a little bit misleading, for me unhooking external USB drivers, while booting, and connecting them back, when system was fully booted, resolved this problem.
