IDE DMA and packet loss annoyances

So I've been using a DWL-520 and hostap as an AP for a while now, and 
over several kernel/hostap versions I've had problems with packet loss 
while an IDE drive is being accessesed with DMA on.

When I turn DMA off it goes away, but I don't want to do that.

I checked /proc/interrupts, they're not being shared.

Anyone have any idea what's causing this?

I can produce streams of /proc/* and lspci etc output on request.
