I've seen something that may be related with a disk on a PDC20269 based
IDE controller. The disk initially came up under DMA, but experienced a
DMA error and DMA was disabled for that disk. My motherboard is ASUS
A7N8X with an nForce2 chipset. I'm trying to recreate it but haven't
had any luck.

This dmesg output dosen't contain the messages from the DMA loss.
Unfortunately that dmesg output was lost. I'm including this one to
provide system configuration information. There is also an output from
/proc/interrupts at the end.
