The oops will probably fixed the above commit. I don't have much idea
about the DMA problem on 2.6.24 tho. But even with the above commit
fixed, I doubt it would work. The buffer allocation code is broken
and reliably triggered OOM on my test machine. While trying to locate
the bug, I realized the complex code didn't do much good to begin with
and just stripped it down, so I didn't actually tracked down the
actual bug && the patch to simplify buffer management is way too large
for 2.6.29, so unless someone is willing to hunt down the bug just for
2.6.29, we're kind of stuck. :-(
Thanks.
