Users experiencing PS3 Freezing after Update 4.0

Several users who’ve installed the latest firmware update released by Sony are experiencing freezing issues with their console.  According to a thread at reddit, one user’s PS3 slim completely stopped working after switching to the latest update. Here’s what he has to say:

I have a PS3 slim. I’d say it’s about 2 years old. I did the 4.0 update yesterday morning, played about an hour of Dark Souls, and turned off the system. I come back an hour later and turn on the system and it freezes up on the PS3 menu screen and is pixelated. I reset the system and now I get no video and the controller doesn’t seem to sync up at all. Restarting it after this does nothing. If I leave it off for a good 30 min I can get to the menu screen before it shortly freezes up again.

The comments also suggest that others have encountered a similar problem after installing the update of varying degrees. Some people are especially encountering this problem while playing Modern Warfare 3 or Skyrim.
