I still can't reproduce this and I have no idea how to solve it
even if I can reproduce that on my box. :-(
There could be a wrong in DMA configuration or some mis-programmed

Maybe you're not using latest stable/7.

Looks like your kernel is out of sync with world.

It may not be related with DMA error. ale(4) was MFCed to stable/7
so it would be better to rebuild your box with latest stable/7.
