[c-nsp] Cisco WS2960-X - Are these switches lemons or is there a stable release?

[Hagen AMEN]

Certainly, we saw the issue happen running 15.0(2)EX5, but we've also seen
it happen on 15.2(2)E, 15.2(2a)E1, as well as ES releases from TAC (which
were supposed to fix the issue).

We're running 15.2(3)E1, for the last couple of months (July timeframe). So
far, no recurrence.
