[c-nsp] GSR 12008 CSC-8 issues

[Robert Geller]

The show controllers fia showed all zeros.  Furthermore, show led and 
show env led showed OK when we were amber.  When we were having the 
issue when we pulled out the CSC, we saw log entries of all sorts like
slot X download IOS timeout, spurious memory errors, traceback etc.
The cards kept trying to reload and couldnt.
