Adam,

Sorry I should have been clearer in my original post.

I had made dumps from one machine from each individual file system

/        (dev/da0s1a)
/var        (dev/da0s1d)
/usr        (/dev/da0s1e)
/home        (/dev/da0s1f)

Then, on a different machine, was dumping them using the LIVE FS CD boot 
disk, to it's primary drive that was pre fdisk'd and the filesystems 
created.

The root, var filesystem restored fine, but, as I said, the usr filesystem 
keep crapping out with the errors mentioned.

I even get the same error when trying to actually install freebsd from CD, 
from scratch.

Yesterday, I ran every diagnostic available to the system (Dell 32 Bit 
Diags, on board controller diags, etc) and they all passed with no errors.

I have seen some scuttlebutt white googling, about the SAS5/IR buuffer 
problems, but have not seen a resolution yet.
