I'm having similar problems trying to copy 1/2T of data. The system is repeatedly freezing during a "cp" command. (12.04.2, fully updated.)

I've noticed this problem under two separate installs of 12.04 64-bit, on two different SSDs. There seems to be some race condition exposed by the pure speed of the writes?
