Verbose boot does not give any more information.
When I tried to mount the d partition in another dragonfly machine I
got the error.

#mount /dev/ad8s1d /mnt
hammer:mount   on /mnt: Input/Output error

Running a smartctl short offline test completed without any error I am
running a long offline test now.
