   I turned off preemption and now i don't have messages about ad0,
   but messages about ad4 and ad6 still appear(but not so often) :
ad6: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=591
ad4: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=591
ad4: TIMEOUT - WRITE_DMA retrying (2 retries left) LBA=148701391
