I guess it could be a pair of DMA buffers where another buffer gets
processed with CPU while another buffer is filling... and when the second
buffer is full, the buffers are flipped.

As far as I know (and I really don't know much here...) kernel does not
reschedule while in system call (ie. inside kernel). This would make the
machine to hang.

Don't. 2.0.x should be just fine :)
