Might be a clue. My laptop has this: ad0: 19077MB at ata0-master UDMA100 Typical errors: Jul 23 15:00:33 auricle kernel: ad0: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=20586350 Jul 25 09:01:52 auricle kernel: ad0: TIMEOUT - READ_MUL retrying (2 retries left) LBA=1731115 I had been running 4.X on this box with no DMA problems until I put 5.3 on it many months ago. It also boots Windows XP, and I don't have any obvious disk problems with that. Do you have trouble with the touchpad occasionally going nuts? I had mine replaced, and it still does it. With any OS I care to boot. I have some Firewire-related problems, too, but I won't go into them right now. -- J. Porter Clark
