I remember having to tweak it a bit to get it to play nicely. IIRC 5.2.1 does not have apic in by defualt? I may just haved removed it... I forget now, but any ways. Before trying apic, make sure your kernel has it. If your kernel does not, go into the setup screen and turn it off. I never had any ACPI problems with it and that has all ways worked well, minus a warning about a odd character or the like in it at startup. I also ran into another problem of my board not liking two ram sticks in dual channel mode... would cause a lock up around booting... iirc it would nearly finish and then lock up and KB LEDs would work a bit. So far my only complaint with it has been the onboard vr ethernet chip appears to suck compared to the dc pci card I have been using. Not taken the time to sort that out yet. Appears some what slow under heavy load. Think that has to do with a problem with device polling for that chipset.
