Fedora 16 : fix hanging Fedora when rebooting

My Fedora 16 device sometimes hangs when rebooting.

Fedora 16 64bit
ONKYO M513A5P ( laptop )

Seen from Fedora’s documentation , I could solve this issue by adding kernel options like this:


System hangs on reboot

Changing the reboot method can work around this problem. To force a reboot method other than the default, use the reboot= kernel option:
  • reboot=b forces reboot through the system BIOS.
  • reboot=w forces a 'warm" reboot (no memory test.)

These can be combined: reboot=b,w forces a warm reboot using the system BIOS.

edit /etc/default/grub file.

b : bios
a : acpi

update grub.cfg
# grub2-mkconfig -o /boot/grub2/grub.cfg

( in case of Ubuntu based distribution , issue update-grub2 )

reboot the Fefora device to reflect kernel options.
# cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-3.2.7-1.fc16.x86_64 root=/dev/sda1 reboot=b,a
