On ED-E my love quest when you are prompted to go to the brotherhood of steel bunker and try the password, I go to the bunker and get inside the paladin approaches me and askes me to give over my gear which i do..... the minute i hear the gear change hands ... the game locks up....

If i had to venture a guess I would say it has to do with the NCR radio in my gear, you cannot drop it at all so im thinking there is a prob with that....

Figured this one out myself by dropping all my weapons in a bin before talking to the paladin....
