Sure thing, the TAC case I believe was 600378549. So many versions of code
were used that I can't remember them. But the exact commands you indicated
below were used on the platforms that failed to operate correctly. I have
since replaced the 4 routers I was having trouble with, so I don't have
their SNs anymore.
Thanks!

Please provide more information so someone can help if they are willing...
ie:
version of code
sh diag for platform information
TAC case # if you have one for reference
I just tried one in the lab:
