I find out that I just can't set the acpi_osi="!Windows 2012" properly
Grub2 will second guess the quote and change it. So it end up Linux kernel will
see "acpi_osi=!Windows\x202012" or some thing like that.
However, I just find out that if I set acpi_osi=Linux the black screen
will go away.
That is one usable work around on the stock fedora kernel.
