Same problem here.
However, the memory test did not resolve the memory issue (no errors reported), as mine would reboot with the new ver , and then go on playing. (it also took mine 5 minutes to boot up, and the audio artifacts would actually cause my unit to hang, and not reboot. All after about 30 minutes of playtime.)

So regardless, my unit is currently flying over the pond (as of this post), back to its origins, to get repaired.

I only hope I don't have to wait too long!
