According to Electronic Arts, the PS4's 1.50 firmware can cause a PS4 to malfunction.
"Sony has released a firmware update for the PlayStation 4 that is required for many features on the console. However, this update also results in stability issues while playing games on the system.
This affects all games on the PS4, including EA titles, causing crashing/freezing and non-responsive connections between the player's console and their TV Screen."
UPDATE: EA took down the link! Most of the text of the (now dead) link is quoted above.
The rest of the text is here:
"Unfortunately since it's an issue with Sony's firmware, it requires a new update to fix it. Sony is working to resolve the issue as quickly as they can. They will update their System Update page as new versions are made available, and we will keep this page updated as we find out more."
