On my onboard pmac controller, it either hangs, with "lost interrupt"
being repeated, or resets ide0.
I thought that it might be because you've changed DMA_TIMEOUT to 100
from 500. When I recompiled with 500 again, it didn't change anything.
The driver pmac.c simply cannot get a dma, and doesn't have multicount
enabled.
