As far as I can see, the only relevant change between my last working kernel and the new one is a fix for DMA with the pcm driver (RealPlayer now finally works, thanks Grant). Here is what I get: ad0: HARD READ ERROR blk# 46887ad0: DMA problem encountered, fallback to PIO mode ad0: DMA problem encountered, fallback to PIO mode ad0: DMA problem encountered, fallback to PIO mode ad0: DMA problem encountered, fallback to PIO mode ad0: DMA problem encountered, fallback to PIO mode ad0: DMA problem encountered, fallback to PIO mode ad0: DMA problem encountered, fallback to PIO mode ad0: HARD READ ERROR blk# 46999 status=59 error=01 ad0: DMA problem encountered, fallback to PIO mode DMA was working fine on this motherboard (Intel AN430TX) and disk (IBM DTTA-371440) before the recent kernel upgrade (which was done two days ago). Any ideas?
