12.2(33)SCB5

Description (partial)

Symptom:
 On a 10k running 12.2(33)SBC5 on PRE4, after a redundancy linecard failover
and revertback (HCCP), one might see something like the following in the
syslogs.  It appears to occur after a hw-module reset of 5/1 in order to bring
the modems from the protect back to the working.  (i.e. during a boot-up of
CLC5/1.  Perhaps related to defaulting the interfaces on CLC5/1.)

 This looks similar to CSCsu77276 and does not appear at this point to be
impacting the modems affected by the redundancy failover and revertback.
 
 
 Conditions:
After a hw-module reset of CLC 5/1, and then a redundancy linecard failover and
