I own a Abit NF7
Yeah... I remember this. A bit... 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.
