This is why I would say that firmware updates are part of the preventative 
maintenance in the same way kernel updates are, if the bug was already fixed 
and if you had flashed this during a normal maintenance window you never would 
have had an unplanned maintenance to fix or recover from the problem.  
Manufacturers don’t tend to update firmware without real bug reports from the 
field, why wait until you’ve had a failure due to some already-fixed corner 
case.
