He's offered to help track this down. Thanks I'll try contacting Scott. In the meantime I think I have narrowed down the problem in my case to the on-board Promise SATA controller. My motherboard has 2 SATA controllers, one Promise and one Via and I have 2 sets of disks with gmirror RAID 1 - 2xSeagate Barracuda + 2xWD5000YS. atapci0: atapci1: The Western Digital disks were connected to the Promise controller and giving the READ_DMA TIMEOUT errors, I've now swapped the disks around so the Seagate ones are attached to the Promise controller and now these are reporting the errors. So it seems I can definitely exclude disk hardware problems. -Gianni
