DMA timeouts on ad0 (amd64)

[Conrad J. Sabatier]

Although the situation seems to be gradually improving with successive
updates, I'm still seeing a fair number of these:

ad0: TIMEOUT - READ_DMA retrying (2 retries left) LBA=83419448
ad0: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=83325504
