Description
Returning zero for this call causes some OSs to kernel panic
See second screenshot down. Text reads: "Determined CPU:FSB multiplier to be 0. CPU says it's multiplier is 0 which makes no sense. The kernel as it is shipped by Apple will not support this and will cause the machine to reboot immediately. Press 'y' to continue or use Ctrl+Alt+Delete to reboot."
According to http://www.tgwbd.org/darwin/index.html, this causes a divide by zero in the kernel and a resultant kernel panic.
Please note that I am virtualizing using Mac hardware.
