If this is widespread, I think the chances re slim that it is a > hardware problem in every case. I noticed this week that I was getting DMA WRITE timeouts on two of my disks on my 7.0-RC1 box. The strange thing in my case was that only 2 of my 3 drives were exhibiting the behavior. The two having the problem were both SATA300 drives, while the third was SATA150. I jumpered the two "bad" drives to SATA150, and the timeouts went away. I replaced the motherboard, set the two drives back to SATA300 and have not had a timeout since. I was thinking maybe it was related, but in my case it was truly a hardware failure. Here were the messages, for what it's worth: Jan 23 10:05:01 pflog kernel: ad10: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=1525567 Jan 23 10:05:09 pflog kernel: ad10: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=3828159 Jan 23 10:07:27 pflog kernel: ad10: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=3450111 Jan 23 10:07:33 pflog kernel: ad10: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=4561983 Jan 23 11:30:27 pflog kernel: ad10: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=4178303 Jan 23 11:30:33 pflog kernel: ad10: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=5660287 Jan 23 11:30:39 pflog kernel: ad10: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=6805951 Jan 23 11:30:48 pflog kernel: ad10: TIMEOUT - WRITE_DMA retrying (1 retry left) LBA=9856959 Josh
