So far so good. Unfortunately, I had to make 2 changes to the box
showing the problem the most. I changed the cable (the new one does seem
to fit more snug) as well as updated the code.  I havent done many level
0 dumps to it (the real test will be the weekend), but so far so good.
On the other box that did show the same READ LOG EXT error, I also
updated the kernel, but made no hardware changes. It too has not yet
shown any errors since the upgrade.

I changed the cable at 8am local time yesterday, and I take snapshots of
smartctl at 5am

I did see this error increase in 24hrs, but that was on a disk that was
off the motherboard.  Perhaps a new cable for it too.
