Hasn't the CF6 always had problems with poor resistance to FOD, catastrophic engine failures and so forth?
This isn't the case at all. CF6 engines are no better or no worse in resistance to FOD damage than other engines.
You are going to see more and more FOD damage to engines, all sizes and all makes and models. The reason is birds. There were 150 severe bird strikes reported in 2009, up 40% from the average 2000 through 2008. The increasing trend applied to 2010. More birds are hanging out around airports than ever before. Recently, I was waiting for a flight from Palm Springs to SLC. When the plane came in to Palm Springs, it hit a flock of birds causing some damage to one engine and lots of dents to the right wing LE slats. Its not unususal these days.
As far as uncontained failures go, these are pretty much spread around among the engine manufacturers and are the result of various causes. See the Qantas Airbus A-380 uncontained failure thread for the most serious recent event.
