[Bug 499497] Re: reboot=pci boot parameter required to reboot iMac10, 1

[Jason Edgecombe]

apport information

** Tags added: apport-collected

** Description changed:

  The system will power off fine when using the "poweroff" command, but
  when rebooting, it will hang when the machine is supposed to power-
  cycle.
  
  adding the "reboot=pci" kernel boot option allows reboots work work
  normally.
