At least its an indicator that their is trouble with the cpu (PIO transfers all data through the cpu).

I find it more likely that being in PIO mode would cause things to hang, since the CPU is too... inundated with data--it's too busy. DMA isn't going to decrease stability, really; PIO is simply slower, since the CPU does need to be the liason for all memory access operations, or so to speak. (Plus, I've had similar issues before on IDE devices; having both IDE controllers in PIO mode makes all sorts of intensive things crawl.)
How ya doing, buddy?
