patch to disable data-corrupting 64-bit DMA on atl1

Can you attach your .config for me?

Can you apply this patch to gentoo-sources-2.6.22-r6, test it and post the results here?

> ...i'm trying to apply this patch.....

copy the patch to /usr/src/linux or wherever you compile the 2.6.22-r6 kernel and type:

patch -p1 < atl1-disable-broken-64-bit-dma.patch

then make and install the kernel as you normally do
