The BMC depends on PS_PWROK de-asserting to know that the system has 
shut down.  If the Graceful power-off timer is expiring, it means that 
the BMC didn't see PS_PWROK de-assert.

Holding the power button should cause the power button override forced 
shutdown in hardware.  It sounds like this isn't happening correctly on 
your system.  I'd suggest reaching out to your Intel representative to 
get help investigating what is happening in the hardware to prevent the 
power button override from fully shutting down the system.
