THis is the output from a new scrub. It is the second scrub against that
data set. The errors that remained after the first scrub (above) have
vanished. I'm a little confused although I often run multiple fsck
against volumes before entering multi-user mode.

That said, during this scrub the system froze twice requiring a reboot.
This is now a common problem across my four AMD systems: one eight core
x1 8150, one 16 core x1 6272, one 16 core x2 6274, and one 16 core x4
6274. (3x r241015M and 1x r241040).
