The ugly nforce IDE DMA with APIC enabled bug has re-emerged on my system
Kernel 2.6.4 fails, they hard lock linux no ctrl-alt-delete, music goes
bzzzzt then stops. I have to either 6 seconds on the power switch or hit the
reset switch to reboot. This usually occurs within a few minutes of booting
or faster if I force a large disk read or copy.
Windows 2000 with the Asus provided drivers works fine.

Almost the same here.
I cannot reproduce the issue on my asus a7n8x with the same HDD &
installed OS, only on biostar M7NCD Pro. a7n8x has an Barton 2500 with
166MHz FSB, m7ncd has an XP 1700 with 133MHz FSB. The machine freezes
completely, the IDE activity led stays on.
It also happens if I disable APIC in the BIOS or passing noapic to the
kernel
A dd if=/dev/hda of=/dev/null freezes the system almost immediately.
Fedora Core 2 Test1 with kernel 2.6.1 seems working, also 2.4 series.
Debian's and stock 2.6.3 works like a charm, but stock 2.6.3 freezes.
2.6.5-rc3-mm4 shows the same sympthoms, dd causes death almost
immediately.
Back to stock 2.6.4:
It seems that disabling both ACPI and APIC in the kernel config solves
the problem
hdparm -d0 also solves the problem but performance is awful without DMA
Finally it seems there is a solution: I've updated the patch
http://www.kernel.org/pub/linux/kernel/people/bart/2.6.0-test11-bart1/broken-out/nforce2-disconnect-quirk.patch
to be able to apply to 2.6.4 and now everything is working flawlessly.
Can anyone enlighten me why isn't it merged to the mainstream kernel
yet? I've found lots of people with the same problems while searching
for the solution to mine, so it seems a common problem with some nforce2
motherboards.
Here is the modified patch:

Perhaps because Ross Dickson's patches seem to fix the problem without
disabling those power saving & temperature reducing features. But
there is no consensus yet, so you might want to try out his current
patches to see if they solve your problem, and give feedback.
