Hmm. Something seems missing here. Chipset-specific driver not enabled?
I don't see any references to DMA mode or the controller type. It seems
like in this case something in drivers/ide is blowing up later on (which
shouldn't happen in any case but that code is not the greatest).
Myself, I would try disabling CONFIG_IDE entirely and enabling the
corresponding new libata PATA driver for this chipset's PATA ports (for
nForce4 it will be pata_amd). Even if it still doesn't work it may allow
the real problem to be diagnosed more easily.
