Thanks,

I find it kind of funny I tried the 4-5 options that didn't work first, 
bad luck?

Here is what worked and what did not and what I ended up using:

reboot=a * SUCCESS
reboot=b * FAIL
reboot=cold * FAIL
reboot=efi * FAIL
reboot=force * FAIL
reboot=h * FAIL
reboot=p * SUCCESS
reboot=s * FAIL
reboot=t * SUCCESS
reboot=warm * FAIL

I am using reboot=a for now, until INTEL releases a BIOS fix for this bug.

> From Bryan:

Try each of the following in the reboot= parameter: acpi, smp (32-bit
only), triple, efi, pci, warm, cold, force If one of them works, report 
it, along with the output from dmidecode and lspci -nn, so a workaround
entry can be added.

dmidecode & lspci below--
