With Andre's IDE patch and 2.4.17, my machine locked up when
compiling 2.4.17 with both the DMA on and the DMA off.
With patch-2.4.18-pre9, the machine only locked up when
DMA was set on, with DMA off, I could recompile the kernel
as many times as I wanted.
Following are kernel messages from the kernel boot with
Andre's IDE patch.
