    275    On some systems, hibernation refuses to work if ACPI is enabled. You 
    276    can disable ACPI by adding "acpi=off" to the kernel arguments. 
    277  
    278275   Alternatively, once the system is running, you can activate hibernation by 
    279276   echoing the major and minor numbers of the partition to /sys/power/resume as 
    … …  
    304301(even read-only, because there is no true read-only mount on journaled 
    305302filesystems)! 
     303 
     304   On some systems, hibernation refuses to work due to a broken ACPI 
     305   implementation, with the following message in "dmesg | tail"  output: 
     306 
     307       acpi_pm_prepare does not support 4 
     308 
     309   Possible solutions: 
     310 
     311   a) run the following command before hibernating the computer: 
     312 
     313       echo shutdown >/sys/power/disk 
     314 
     315   b) disable ACPI completely by adding "acpi=off" to the kernel arguments.
