the P3 machine with the Apollo pro chipset is using
the 686B southbridge and might
share the DMA problems. Anyone know if this is a problem?

As I understand it, the elevator should be dealing with the interleaved
nature of the writes. This seems to be working ok for reads, but it
doesnt seem to be working properly for writes.

2.4.0-test, the max_bombs value has been eliminated so I can't change
it. I was hoping that that meant that the algorithm had been improved.
Unfortunately, the benchmarks don't show any improvement.
