Subject: Possible fix for NFORCE2 IDE hangups

Hi.

I have an ASUS A7N8X Deluxe board and had those annoying hangups when
the system had high disk activity.
I tried to reduce the UDMA level or even remove the amd74xx driver from
my kernel and run the system with PIO, but the system still crashed from
time to time.

Last weekend I disabled the use of the APIC (the system now uses XT-PIC)
and this seems to fix the problem. The system ran stable with UDMA100
enabled for the last 4 days.

HTH,
Jens

Yes, exactly the same experience. The frequency of crashes decreased,
but the crashes were definitely still there!

Did the famous "spurious interrupt" messages go away too?

What does it mean for enduser if he disables APIC?

I would try it, but I have returned the PC back to the shop for a
warranty repair because I assumed the southbridge is simply wrong. They
told me they'll replace the MB with KT400A piece.

Is it possible to download nforce2 datasheets somewhere?

Is it possible to download KT400A datasheets anywhere?

I'm just waiting for anyone to make a GPL chipset.

Running without APIC here on an MSI board I still get that message. But I
also get that same message on a bunch of different computers and it is not
harmful, so I don't worry too much about it.

Thanks,
